No real issues with HT2 myself, BB’s seem to last about a year on my MTB and a bit longer on my road bike. At £15 for the most basic shimano BB from my LBS it’s not costing me enough to worry about it all. Never had any frames faced and just bang them on and tighten them up a bit, I ride plenty and in all conditions, perhaps I’m just lucky or maybe I need to be fretting a bit more. Having been through ST/ ISIS/ octalink, I do get a bit tired of the constant changing of standards, but what you going to do. You can still get all the previous systems, so you pay your money you take your choice, I can’t see much point crying about it.
