Hi Rangeball, I surf a bit, but can't spend a lot of time chatting. My heads are out enough now that guys using them are good to answer questions, and they do a good job and I appreciate it. There are a couple reasons my heads blow big holes. One is that they are 1 1/8" 4 blades. That is a total diameter cut of 2 1/4". A 1 1/2" 3 blade, if you do the math, also cuts 2 1/4". So you cut a lot. A 1 1/8" 4 blade cuts 33% more than a 1 1/8" 3 blade. Most people are shooting 1 1/8" or 1 3/16" 3 blades. Keep in mind that 4 blades of the same diameter are certainly better than 3, as they create more open holes, same as a 3 blade opens a better hole than a 2 blade. The X cut pulls open easily and stays open. Forget who posted above about the blade angle, they were correct in that it helps cut a larger hole. As the head enters, with the angle of the Slick Trick blades, hide or flesh is pulled back over the length of the blade. The length of the blade is greater than the height of the blade. So you are cutting a width greater than the 1 1/8" diameter. When you use very long heads you don't get this effect, and when you use heads with blades at greater angles you don't get this effect. Additionally, Slick Trick blades are at a slicing angle instead of the chopping angle of some mechs. So it isn't voodoo, the guys reporting the big holes aren't crazy, its just solid physics at work in the design. My heads were shown to the industry in 2000, the heads you have been seeing since then are the result of imitation being the sincerest form of flattery. That is to my advantage, as without my patented Alcatraz Bladelock nobody can make a head that blows the 4 blade holes mine do, with the aerodynamics I have, and the strength and easy blade replacement. The bonus is that even though they blow the big holes, they still penetrate as well as 3 blades. I am working to expose them to dealers, and meet the demand this fall so they aren't secrets any more. Hope that helps, THANKS GARY
