i just got my rytera alien x back from the bowshop today. had new limbs put on it. only had to wait 2 weeks minus 1 day. not to bad for the limbs coming from wash state to Pa. by the looks of the limbs rytera must be using martins new powertuff limbs and not the barnsdale limbs anymore. the limbs have the slot cut in the limb where the limb bolt goes thru, just like all the other martins. i hope they will hold up as good as the barnsdales.
