i've been able to fix the hole shot issues on the legends.
with my 15" setback, it cuts the hole shot time down to 4-5 seconds and runs mid 70's
after some slight prop tuning.
as far as cracking issues.. idk. haven't heard that.
if your in that 65K price range.. consider the Bullet XRS. you'd be surprised at how
well it rides and fishes. it's much heavier than the older bullets. just a thought.
