Not mathews related-

If you have room for it (or an adjustable cable rod), the rollers on the " alpine glide slide" cable slide provide for a smoother draw -imho.
I had it on my mighty mite and it stretched far enough to put my cable into the path of my fletching. It was replaced w/ a simms.
I just installed it on my stalker and it seems to have more than enough room for any stretch, time will tell. I love it' s smoothness, hate it' s stretching.
