Didn't read every post in the thread, but for my money, it is hard to beat the old Turbo saddle for a general purpose, durable saddle ---- I can squash a Ti railed saddle in one ride , but the Turbo saddle will last a year of hard use (or 10 years on a track bike when you only see the track a few times a year)
I buy NOS and gently used 20+ year old Turbos pretty frequently on ebay --- The sit-bone measurement seems to be pretty lose to a Flite saddle, but they seem much much more comfy (and durable)
