Ibby trems usually fit the radius of the necks better since it's their trem designed for their guitar.
JB's have floyds which are bodged to a different radius (Floyd is 10" JB is actually 14"). Even a great setup it's not purpose built for the JB.
Thats my theory anyway
Well, I know that they shim the bridges to fit with the radius of the guitar for OFRs, at least I think they do. Last I remember I asked Chris Hong about it and he said they did, but i dont remember exactly because it was a long time ago.
