The difference between all 3 of the autoFlex models would be the target audience, as one model may result in better performance for certain players, whereas another model may result in better performance for other players. Ultimately, a premium golf shaft should feel good and right to the player's body. 

Both of the newer generation(Dream and Joy) shafts carry the same concept as the Original (easy to swing and increase kick at impact), but the materials have been upgraded to the latest and greatest carbon prepreg material from Japan for both, which has allowed the shaft to feel even better. Their KHT (Korean Hidden Technology) is now in their 2nd generation. This is their special sauce, we don't know how, we just know it works.

We have posted the recommendation tables on each product-page for reference.

Original - The stiffest overall, has the original autoFlex feel.

Joy365 - Softer feel in the hands than the original and even more kick - designed for slower swinging players to help gain the most efficient height while being very easy on the hands (ex. ladies and seniors)

Dream7 - Slightly softer than the original but with an upgraded tip section for more stability and power at impact.

In such cases, we then ask you about your swing transition style:

- If your swing transition is aggressive/rough, then go for the higher flex of the two

- If your swing transition is smooth/slow, then go for the lower flex of the two

The intent of the manufacturer was for a shaft to provide distance and accuracy with a smooth swing; and not maximum effort with every swing.

CAUTION: High swing speed golfers should not attempt to swing lower spec Autoflex shafts that are more flexible. It may cause the shaft to bend and fracture if swung too hard. (i.e. SS 110+ mph golfer should not try to swing the SF305X or the SF405 hard.)

Roughly speaking, swing weight is the measurement of its balance point based on a scale using a 14″ fulcrum (which most golf shops should have). The metric is represented with a letter (A to F) and a number (0-9), where A0 is the lightest swing weight possible and F9 is the heaviest. Each club has a different swing weight based on shaft weight, length, head weight, grip weight, and other various factors that are unique to your club. You may need to adjust components of your club to land your swing weight within the recommended swing weight range listed on our website for your shaft. Some ways you can adjust swing weight are:

1) -2g off of head weight = -1 SW

2) -1/2" off butt end of shaft = -4 SW

3) +5g grip = -1 SW

and the opposite is true (example: +2g to head weight = +1 SW)

The recommended swing weight for woods is between D0~D2, for irons between D0~D1, and for wedges between D1~D2.

The unique characteristics of Autoflex shafts make it lighter than conventional shafts with a much lower cycles per minute. Due to the more flexible nature, a higher swing weight may cause the club head to wobble on the downswing transition. This may result in an off-centre impact for loss of distance and accuracy. A swing weight of D1 is found to be good for many golfers, but some have seen excellent results at D0 and even up to D3~D4 (for sf505x and xx shafts). Try various swing weight configurations to see what is optimal for you and your swing type.

Counter balancing the grip end can help achieve the swing weight, and it may be helpful to some degree (ie. If the swing weight only needs to decrease by 1 point). However, if the swing weight is too high, adding weight to the butt end increases overall driver weight. Also, the club head will still be too heavy despite the “correct swing weight”, so it may still move too much during the swing. It is better to see if your driver head has inter-changeable weight kit with lower weights. Also, some golfers have mentioned filing down their current weights.

The raw uncut length is 45 inches, so when fitted to a driver head, the shaft length comes to about 46.5~47 inches. There is no ideal length and the butt end can be trimmed to make any total driver length depending on the individual golfer preference (between 44~47 inches).

No. The Autoflex shaft was not intended to be only used as a long drive shaft. Rather, Dumina Co. intended the shaft to help make the game of golf easier by helping slow an average swing speed golfers swing faster without swinging harder. Having said that, the Autoflex shaft line-up can cover from 65mph to 140+mph swing speeds and is used in long drive competition.

Most golfers that have seen success with Autoflex have reported higher launch angles. This is due to the lower cycles per minute (flexible) shaft kicking at impact for an uptick in dynamic loft.

Thus, the higher ball flight is not due to an increase in back spin, but higher launch angle. So the higher launch angle coupled with low spin will provide more carry distance with roll distance.

First thing to check is to see if you are impacting the center of the clubface. Autoflex does not guarantee a center strike every time. If it seems that you are way off the sweet spot, be sure to check your swing weight (swing balance) to see if the head feels too heavy. As mentioned above, Dumina recommends swing weight between D0~D2, with SF305 and SF405 being closer to D0~D1. But if you do not see distance gains and way off-center dispersions (inconsistent impacts), then try to further lessen the swing weight. Some 110+mph hitters have reported that D0 (even C8) swing weight stabilized the head even more for speed and accuracy. Next, check your angle of attack to see if you are in the negative loft. Unless you have a faster swing speed (in excess of 110mph), a positive angle of attack will be more beneficial in getting the ball up in the air with less back spin. In hitting up on the ball, some found that moving the ball an inch or two toward the left foot at address helps to hit up and create a positive angle of attack.Lastly, check to make sure the shaft is not cracked or splintered. If damaged, the shaft may not be able to deliver the proper load and release on impact.
