OK, ok.. so I've considered nearly every possible Co MO frame for my upgrade. I think the Periscope and Cappuccino are out of the picture, but that leaves the very dangerous Aluminum vs. Steel (is real) quandary. The CO Mo steel frameset gets good reviews, but I understand that since I'll have S&S couplers I won't get the top air hardened steel. ON the other hand, the Easton Al tubeset doesn't seem to change whenb the couplers are used. Al is 2# lighter than steel, but of course harsher. I have a Cdale, so the Easton tubeset will be less harsh than that, I assume. SO rail away, any experience you can share will be appreciated.
