RE: MATHEWS FX VS. HOYT MAGNATEC
I have only handled the Magnatec, though I have owned simmilar Hoyts in the past. With the Mathews I have had 4 bows of that type. 3D Hunter, Signature, UltraLight, and FeatherMax.
The easiest way to describe it is as a Mathews/Hoyt thing, if you know you prefer one of those brands then they are pretty typical of them. Pro for the Hoyt is that it has basicaly all the features of a current Hoyt, but with the cheapened riser, not Aluminum. I hate magnesium risers, based on sad past experience, but this is magnesium at a level we couldn't have imagined ten years ago.
With the Mathews, quality-wise you get everything the current bows are made of, but you don't get the latest bells and whistles like limb position, and dampers, those things really aren't all that important, though they are certainly feel improvements. The Maxcam is a good cam, but it isn't a fun cam. It also really helps to know your draw length since it isn't adjustible, if I had never shot before, that lack of adjustibility would kill the Mathews for me. They used to have adjustible cams, at least a little, I don't know why they don't have them now.
For me I would definetly go the FX route, but everyone has to decide what works for them, one thing is that while the Hoyt grip is OK, it isn't all that customizeable. With the Mathews the low grip isn't bad, and they can be reshaped easily, and there are good aftermarked grips available. The grip is the most important feature on the bow for me. When you are shooting, and you are at full draw, you are looking through the sights, shooting off the rest and nock point, holding a release and the grip in your hands. The only part of the bow you are really aware of is the grip, it better be right.
