how many of you guys replaced your xl motors with new bearings?

[blueb8llz]

i was wondering if any of you guys replaced your xl motor bearings with some ceramic one such as boca. i want to know if i did anything such as faster speed, more torque, run smoother, run cooler, etc..
someone from another forum highly recommend them and told me The originals are cheapos and a good Boca will increase lifespan 1000%. The stock bearings will come apart and get into the windings.

and for those of you that dont have them heres a link to them:
whats your opinion on this replace or not to?
