Kind of a throwback to the SC60... I think I like it.
I'm digging it, really like the curvy middle. It looks like very fine knurling in that area which hopefully will be plenty grippy. I'll reserve final judgment until it is in hand but it looks like it will be nicely comfortable.
Regardless, you have to admire the amount of extra machining that went into this new design. Zebralight went the extra mile on this one and I applaud them for it.
