I will throw my 2 pennys in, my Conquest Sti build has Bs removed.
I have put over 10.000 miles on and offroad with no vibration in all rpm ranges. I may be 1 out of 5 but I do agree, the less moving parts the less that (Can fail). Its really up to you and what you feel good about. The 4G64 build I did is also a none Bs motor. My friend builds some of the the best 4G motors with none Bs kits.
Here is one we just finished up <img src="/forums/images/graemlins/smile.gif" alt="" />
