Hey there, I was reading some old posts about bpv and read something written up by Imolas4. In his post he said Bailey = Probably the most popular, serviceable, and that Hyperboost HX = Newest, very cosmetic package, new internals, not serviceable. It said that when a valve is serviceable it is usually mandatory and requires oiling the valve periodically. By having a serviceable valve is it going to last longer then a non serviceable or is a non serviceable valve going to last just as long but requires no maitenence? Thanks for any info and if you guys recommend any other bpv let me know
