first i need to say thanks to to brian at martin archery. left message friday afternoon about an issue with my alien z about the roto limb cup that kept popping after several attempts to remedy the problem. after describing the issue he said he will send me new cups free-of-charge and that will alleviate the problem. always have heard how impeccable martins customer service is. wow, now i know first hand. now the title question. didnt know whether to post this in martin or rytera forum. love my Z, kinda want to try onza 3 bridged riser. is it possible to use the limbs and cams on the Z, 5X limbs and hybrix cams? since the Z is 2.75 inches longer i know i would have to get longer cables and string made. thanks for any help you guys can provide. God Bless, lee
