Has anyone taken a maintenance course by Cycle Confident or by Bikeworks? Did you find it useful? Did you leave with notably better skills?

I'm 6'0" and have ridden a 60cm Felt road bike (7005 aluminum frame) for several years. The frame size fit me well. The frame cracked and I'm looking for a replacement.

While the 60cm Felt felt good, others note that a 56 or 58cm is better for 6-foot individuals. Does frame size differ depending on the manufacturer? Is a 60 cm Felt frame perhaps smaller than a 60cm Canondale, Trek, etc?
