Have you sampled the ultimate? This is our benchmark for the foreseeable future. A front shift feels nearly identical to a rear shift.

I've always been inclined to avoid front shifts, but that totally went away on my uncle's bike. Then when my Yaw FD rocked up and I was examining it, the huge amount of throw and rub-avoiding geometry got me thinking electric Yaw on a half-step triple... I even spent a bit of time on Excel to find the perfect ratios.
