OMG ! I really don't like this ball, you just don't know where you are with it, after trying the DHS plastic ball and being quite happy with it , I thought I'd try a quality butterfly ball, as this , I thought, must be even better! WRONG! It floats something terrible and in a warm room wobbles like a returned ball from Lentec swing!( Not many that remember that nasty piece of lp I bet ) it seems to take an age to come down, making timing your loop shot very tricky, it's wierd! Hope I've just got a bad box, please let me know if anyone else has the same issues 😣😣
