Personally, I use Muzzy but have been looking at Slick Tricks. I can't imagine anything being any quicker than a Muzzy (being a standard broadhead) and if they fly great for you why change? The only reason many guys change is they have trouble tunning Muzzys to fly correctly. But as far as being quicker than a Muzzy, I dunno about that. Any broadhead today with great shot placement will be quick and humane.
