I posted something like 11.5 seconds over 25m in the Nemos. So they're not lightning, but they ain't slow either. Also found them to be easily the most comfortable of the fibreglass ones so far.
On the specialfins front, I got a pair with the Omer footpockets. Unfortunately Omer appears to have downgraded the quality of these in the last few months (they're 60% of the price they used to be) and I blew them into several pieces in a single session. Up until that point they were pretty good. Karmo at specialfins has been good about the whole thing and replaced the footpockets (which I destroyed again). So now he's replacing them with a custom pair made to the dimensions I gave him. Unfortunately they'll have a strap footpocket on them like the Leaders, but they should be a bit larger than most of the fibreglass fins around. I'll post a review after they turn up next week...
