I think there are plenty of available opinions regarding swing-bar speed, forgiveness, distance, accuracy, etc. on these forums.
In my case, I went from starters, to tour starters, to TM. TM were too fast till I went to new balls. Then with G-ID balls, the swing was too slow, so went to B-XD.
Goldilocks system to find the set that's just right.
Trial and trial again
Cheers,
