HI
I have a 2005 hoyt ultra mag(I bought it brand new)
the ultramag is hoyts "economy" bow
the difference between the "ultra's" and the "TEC's" is that the tec bows(ultra tec, v-tec, ect.) have machined risers while the "ultra" bows have cast recievers.
also the 2004 ultra mag and the 2005 ultra mag are different. the 2005 model comes with "alpha shox" while the 2004 ultra mags have different ones.
The bow that I have shoots great and dosent seem to long.
if you are concerned with axle to axle length; I think that most of the "tec" bows have different limbs you can get like 3000 or 2000, ect.
HOPE THIS HELPS :grin:
