Help me understand the difference between HZRDUS and Evenflow and "tempo fitting"

[me05501]

True Temper says HZRDUS is for aggressive swingers and Evenflow is for smoother tempos. 

 

From a technical standpoint, how are these built differently to achieve those target fits? 

 

Secondly, do you agree with TT's marketing angle on these shafts or have your fitting results been different from expectations?

I think one key metric is balance point.  Higher balance point (some call it "counter balance") plays well with smoother tempos and transitions.  The lower balance points are more aggressive swings.

I think the Evenflow as a line have higher BPs than the HZRDUS line.

 

However, within the HZRDUS line, the green and yellow are noted to have higher balance points.  I'm playing the Yellow 6.0 in my Tour Edge driver and FW.  I like them both and am not an aggressive swinger.

I'm a smooth tempo and play HZRDU Black Smoke.  One of the guys I play with is 75 and very aggressive.  He plays Evenflow.  I don't know how much it matters but it's good to have choices.

In my personal experience, their descriptions hold true. I have a pretty smooth swing, and I can’t load the Hzrdus shafts at all, especially the black. It’s a straight push or dead pull. 
 

I’ve gotten along a lot better with the Evenflow shafts when trying out clubs.

Aggressive transitions load the shaft more (and faster) than smoother transitions so in general stiffer shafts tend to feel better for the aggressive players.   But there is no ideal amount of loading nor is there any one concept of what a good feel is for the player - it's all really very subjective.   You can have aggressive players that want/need to feel more loading or smooth transition players that want to feel less.   That makes it a very rough generalization at best.  There will always be plenty of exceptions so you should never treat that (or any other shaft marketing 'advice') as anything more than maybe a reason to demo the shaft.  They should never be used to make a purchase decisions or treated as any kind of hard and fast rule one must follow.

I use evenflow white in my driver and hzrdus yellow in my 3 wood. Both at 6.5 flex and get on fine with them both.

 

Had a 2 iron with hzrdus black in 6.5 and couldn't get on with it at all as I felt it was too stiff for me to get anything out of it. Also had an evenflow in the green/blue colour in 6.5 in a hybrid and couldn't get on with that either.

 

Just depends on how you get on with the shaft and what feels best to you.

As someone who is aggressive in transition the hzrdus feels better and has worked better than the evenflow line for me.

 

PX designed the original hzrdus line of performance and didn’t take into account feel. When they designed the evenflow line they wanted the performance factor to be maintained but accounted for the feel aspect. This is directly from Don Brown at PX

I tend to agree with their assessment of the two lines. I’m more of an aggressive swinger and get along very well with the Hzrdus line, but for the life of me can’t hit the Evenflow line at all.
