Let me assure you that there is no planing with a slick trick.

I, as well as countless others, have found them to be the most accurate and one of the best penetrating fixed blade head made today. That 4 blade 1 1/8 inch head makes a huge hole and produces awesome blood trails.

I have tried the montecs and they are a great head but they do have a bad draw back IMHO. If you damage the blades they are pretty much shot. They can be gouged up pretty badly by striking small rocks and such in the ground and group tuning and sometimes it's bad enough that you can't get the gouges out with out filing down a large ammount of the blades and changing the weight and weakening the blades.

I prefer a replacement blade head.
