Thought I'd toss it out there...
I've been stabbed one too many times with my Salsa & running it in reverse often catches my shorts; so I'd be interested in swapping my nearly new 32mm Salsa quick release for your factory clamp for a nearly even trade.
I never had slippage issues so it's not a concern for me.
