The Big Hit Pearl has been reviewed 2 different times in BTM Mag. The first time was with the Teal/Purple about 2 years ago... and then about 5-6 months ago with the new colored Red/Blackish one.
But both reviews gave different numbers. Basically the Teal/Purple should be alot stronger than than the Red/Blackish one by what they said in their length, torque, backend, and oil handling capability ratings.
Are they not the same ball?
