1.21 BPF means your bat has limit....
I wish you had finished that sentence because I may have a slightly different take on BPF for seniors.
Without starting any rants, BPF of 1.21 is just the starting point for senior bats.
They get tested as "Brand-New" bats, no break-in, no pre conditioning like rolling.
No testing up and down the barrel, only at the mathematical sweet spot.
What happens after they leave Dr. Brandts office most likely turns into something much better than 1.21, but definitely different performance and durability from one flavor to the next . .....just saying.
I did notice on directsports that the Larry Carter has a one year manufacturers warranty which is a lot better than all the other top players.
