I shot a 7pt. saturday morning with one.I shot the 3 blade.All i can say is that they are awesome.He ran about 75 yards a piled up.The entrance hole looked a 7 mag blew through it.
the only negative thing I am hearing about them is that the nut has to be adjusted from time to time to keep the blades from deploying in flight. other than that, I hear they are awesome! But I personally chose to stick with the fixed blade. Muzzy MX-3s for me
i have no personal experience with them, i too, prefer fixed blades. however, i read a lot of hunting forums, and i have heard basically nothing but good things about them. i have seen some pics of a 2 blade on a deer and it was devastating.
two of my friends used them last year an they said the hole was awasom .you will not be disapointed .from what they told me.i still use 100gain thunderheads.i have great success with these.i know there are some better than these but i get good flight with these an if it aint broke,well you know.good luck.i just got back from a hunt this evening an saw none,going fishing in the morning an back to the woods sat.will let you all know how it goes.
