I used them for the first time this year and they performed well. I've been using Muzzy's for several years but switched because the ferrule on the Slick Tricks is steel. I never had a Muzzy fail but didn't like the aluminum. I think the Tricks are more durable. Have never used Montec so can't give you a comparison. You won't be dissapointed with these heads, I'm not going to take the Muzzy's out of retirement any time soon.

I will add, they will not group with your field points if your bow is not tuned. There was no accuracy difference for me between the Muzzy and Slick Trick.
