Mike from Texas has hit the nail right on the head .I couldn't agree more with what he has told you .I use both head's and the Montec's are a good head,do fly like dart's as mentioned ,but yes they need to be much sharper out of the package . I also use the Slick Trick's and they to have had a bit of a sharpness issue ,butI had a complete passthrough on a bear this fall with thelast season'sversion Slick Trick's .
Both are good head's ,but if it was my choice it would be Slick Trick's all the way.
