I shoot them and will never switch. For me, they are the best broadhead out there. If you are choosing between these and the Montecs, go with the Slicks. 4 blades are better than 3, especially when they are the same cutting diameter. The new blades are scary sharp and just as durable as the old ones.
www.slicktrick.net is the website where I get mine. If someone does indeed have a cheaper outlet,I'm all ears. They are already cheaper than most heads out there.
BTW: most people at the shop where I go don't know about them either,so I wouldn't use that as a reference point.The ones that know about them, most likely use them!
