I echo 98Redline' s comments.

I have a RazorTec and it is smooth. No problems and I' ve shot around 2000 shots through it. Robinhooded 2 arrows about 2 months after I got it from 18 yds and I' ve killed 2 deer and hog with it already this year.

I like shooting it so much that I shoot more often than I did with my old bow.

I' ve had no problems with strings, cables or timing.
