Myself, my wife and about 4 others in my bowclub all shoot the Extreme VFT. No complaints that I have heard. performance wise they are real nice to shoot and will get you some serious speed. I get around 310 out of mine at 30" draw 70#, the wife is getting 297 at 29" draw 46#' s....both these are shooting around 5 grns/pound. Another fellow at our club is shooting the Black Knight, it seems to be quite finicky as he is constantly having to tinker with it. Am currently looking at a PRO 40 for another bow for my wife.... extremely smooth draw, good brace height and ATA. It sacrifices some speed to the VFT but I believe it will be a more forgiving bow.
Hope this helps some!
