Try the search out, you will find plenty of good info on the Montecs.

I have switched from Thunderheads to Montecs this year and am very pleased with them so far. They all spun true (reagardless of which shaft I put them on), and hit with my fieldpoints.

Out of the package they are not terribly sharp, but a bit of work with a flat bastrard file and a finish up with a diamond stone will have them scary sharp in about 10-15 min per head.

I doubt that short of maybe a magnus snuffer you will find a stronger broadhead.
