Some people on the forum talk about how we don't need high gears or we're not worthy of those gears, etc. To me, run the high gear you're comfortable with on the terrain you ride. On my compact crank bike I was not happy with 50x13 and was able to find a cassette with a 12 which helped on big rollers, windy descents and pacelines. On my standard crank bike I have a 52x11 and I only use the 11 on big descents.
