    I have been having major trouble with certain strings being too elastic in my string bed and messing up my shots.

    I am trying to use this String Tool to compare strings, but I'm not sure exactly which features are most relevant to this issue.

    Is spin potential a measure of elasticity? What about energy return? Is stiffness primarily a measure of string elasticity or does it incorporate other factors too?

    I'm assuming that tension loss would be a factor too if I strung at a lowish tension and it drops off.

    Anyway, thanks for clearing this up! What a fantastic resource for players!!

    From the string DB, I normally look at string stiffness, total % tension loss, String-string COF and Ball-string COF. The dynamic data is not useful to me since they were derived from lab setups. Players don't hit like the lab setups so I take that data with a LARGE grain of salt. Stiffness helps me with selecting tension. Stiffness tells me which string should theoretically hold tension better relative to each other. Tension loss % tells me how long the string may be playable before falling off the cliff in terms of control. COF tells me how well the strings theoretically snap back. Ball-string COF tells me how well the string grabs the ball. I really do not pay too much attention to this last factor since a good player with RHS will compensate.

    If the string bed is too elastic, then you have to compensate by increasing ref tension. This is offset by having the rate of tension loss increase because you increased ref tension. I try to pull longer [CP} to minimize static tension losses. Dynamic tension losses will occur, but you won't experience sudden losses of control because the static losses are already mainly pulled out. This allows me to use a lower ref tension. Lower tensions allow the string to remain longer in a playable DT range. It will still experience the tension loss, but slower. That's my concept and it is based on what is going on with pre-stretched poly strings. If you ever played with 4G vs BBO, you will understand about the cliff in string performance.

    If you are using non-polys, this still applies. Only difference is you can use slightly higher ref tensions. Anyway, this is how I use the data. HTH.
