I've never built a bike up (like an earlier poster, my first reaction was "Just buy an already-built LHT, you'll be good to go") so I don't have anything of value to offer the O.P., but I have to say that I'm enjoying the Great Bar End vs. STI War.
(You can have my bar ends when you pry them from my dead, cold (too-tiny-to-shift-STIs-easily


) hands!!)
