Hoyt X Tec with Cam.5 is a medium cam.
I have to respectfully disagree. IME with several of my personal C.5 bows from Hoyt (including the X-Tec) as well as fiddling at the shop there is no doubt they prefer a stiff arrow for best groups/easiest tuning, and going off the medium column on the Easton chart is very likely to get someone underspined.
The only time I would consider using the medium cam columns would be if the particular bow I had was equipped with the XT3000 limbs. For Spiral cams I would add another 5 pounds to whatever peak is and go from there on the hard-cam column.
