What is SensiCore?

SensiCore is a vibration damping mechanism which reduces vibration/shock 70% better than other steel shafts and 25-30% better than graphite shafts. It is 14" long and is inserted 10" down from the butt end of the shaft. It does not effect the playability of the shaft. A club maker does not have to worry about cutting into it when tip or butt cutting. The only drawback is that you cannot swingweight the club using lead powder because you can’t cork it from the inside.

What is flex?

"Flex" is the relative stiffness of a shaft. True Temper's flex designations are (from most flexible to most stiff):

J

L

A

R

S

X

Junior

Ladies

Action

Regular

Stiff

Extra-stiff

To find out what flex shafts you should have with your clubs, find out about fitting yourself for shafts.

What is sub-flex and what is the difference between the sub-flexes?

Sub-flex is the relative stiffness of a shaft measured to a finer degree within a flex category. That is why you'll see flex designations like R200, R300, R400, etc. Weight is the major difference -- 200 is lighter, 400 is heavier. R300, S300, X100 are the standard flexes. About 3 grams is the actual weight difference. For example an R200 may play a little more flexible than the R300 and the R400 may play a little stiffer than the R300 only because of the weight.

How can you make a shaft play stiffer or weaker?
 
bulletTo play stiffer:
bulletParallel tip shafts: Trim more off the tip end; increasing the amount trimmed off the tip by 1/2" will change the shaft about a sub-flex.
bulletTapered tip shafts: "step the shaft down"- since tapered tip shafts come in different lengths, a person can put the 3 iron shaft into the 2 iron club and so on, therefore shortening the tip to 1st step section and increasing the stiffness about a sub flex.
bulletTo play weaker: <
