Maybe I'm a wierdo but this is something that is bothering me for a while. My western forehand is a wristy fast short whip at the ball (like if Sock and Kyrgios had a child with Poliomyelitis). I Can produce a lot of RHS but I lack some plow thru and consistency. My Backhand (by far my best shot, technique wise) is a Eastern grip and I can cross court with a lot of topspin and flatten out some heavy balls too. I Always focused on hitting it more on the snap of the wrist and on the side of the ball with spin like (wawrinka and kuerten) more than the classic haas federer flat slap on the ball. On Both sides, I find myself more of a "brusher" then a "crusher", like to play short angles with **** loads of RHS, so sometimes I tend to brush up more than I drive thru (trying to find the balance between brushing and drivin, but playing in the low forties really helped me to amp my forehand in terms of spin bite and penetration.) I have been playing with the Pure Aero with 1.30 poly at 45lbs. This Low forties simply doubled my FH penetration and spin, I gained some weight on my FH shot from the bite I am getting from low tension poly and the feeling that I can whip it a lot harder. On the other hand, since I went to the low lands it has cost me my backhand. Felt like I lost the ability to swing out hard and to flatten out on short defensive (like RoS) strokes. Found myself running away from my backhand and slicing it more. Lost the control of it and started sending nukes to the fence. I Know, you will say that the solution is obvious: Find the tension sweetspot for both strokes. Went 52lbs yesterday just for experimenting and guess what: My backhand was back, could drive trhu, go big and slap flat when needed. Forehand went from a Bazooka to bb gun. less trampoline and snap back effect that my short fast stroke was feeding on. So I realized this: Forehand Tension Sweetspot is on low 40s and Backhand Tension Sweetspot is on mid 50s. Question is simple : I see that guys that play on low tension and rely mostly on the ball bite and RHS (jack sock as an example) play both of his wings with a technique that favors the mid 30s. Even if you think nadal with his high tension stringing, you see that both of his wings are played relied on the same tipe of ball contact. Then you see Agassi Murray, Safin, Nalbandian all this fellas play both wings with the same ""type of ball contact objective"", making the right string tension for one stroke beeing perfectly suited for the other. Should I work on a forehand that has the same mechanics as my Backhand to find the perfect string balance? Or I will always have to favor one string tension for the stroke I mostly rely, while knowing that 10lbs less would turn a my dagger FH into a Dragonslayer?
