I have been shooting the Montecs this year with very good results. They are a very tough head and fly with my fieldpoints. I really like the idea of a single piece of metal from " head to thread" .
The sharpening of the heads can be a bit tricky, but once you get the hang of it, it is quite easy and takes about 5 min per head.

While some have posted good results with the CTs, I have heard more people taking about their lack of strength on hard bone hits. Things like the ferrule bending or blade loss seems semi typical with this head.

The Rocket mechanical heads are also a very good choice. If you have the KE in your setup for a mech, they can be very effective. The steelhead seems to be the most popular as well as the toughest of the rockets. Additionally it' s 1 1/2" cutting diameter is relatively modest compared to the awesome 2 1/2" buckblaster. For the steelheads, I would recomend no less than 55 ft-lbs of KE to ensure the blades fully open and you get adequate penetration. I have also shot the Rocket Slammerhead with very good results (KE=64 ft-lbs). This head is 1 3/4" diameter with the pathfinder tip. The doe I hit nearly dropped in her tracks (<5 yds from where she was hit). The head busted through a rib, both lungs and clipped the heart.

That' s my opinion, you can take it or leave it.
