as many of you know, i used to own an Alpha Shuttle Express stringing machine and now i own a Gamma 6004 6pt machine. both machine have the same WISE tension head. i just moved it over after i sold the ASE. the ASE is a flying clamp only machine. it is a decent machine, pretty strong but nothing when compared to the Gamma 6004 which is a completely solid beast. for the ASE, i used to tension my mains the same tension as the cross. that was after various experiments and turned out that produce the best feel. feel being how lively the string feel, result is a crisp repulsion that is both powerful and fast. i have tried all sorts of main/cross ratio, including add 2 pounds, add 10%, add 15%. etc. best is still main==cross on the ASE. for the 6004 however, when i string main=cross, the feeling is not as good. shuttle on impact tend to have more feeling of a thud instead of a crisp feel. and it is not just myself who felt that way, my customer also have the same feedback. so i experimented again, and again. and eventually, the tension that works best is cross = main + 10%. after i started this new tension ratio, i started to get that same feeling that i got from the ASE again. and complements from customers have started rolling in again. so why is it? i use flying clamps on both machines. they are being tensioned with the same exact WISE tensioner. the only difference is the turntable. and you also also argue that now i have 360 rotation which means the string is pulled at a slight angle. that's about it. the Gamma definitely has a much stronger support system, all the support arms are beefy as hell and don't budge a bit at all. the ASE on the other hand is very good but not something to write home about. comments?
