An ultratech with 7 3/8 inch brace is not what I would consider a low brace height bow . Sounds like the tech at your shop is not much of a " tech" . If the claw is in the hole closest to the risor you might try putting it in the hole futher away from the risor and see if that works , but as mentioned prevously muzzy has an excellent tech suport and they have bows haging in the shop that work from the major copanies . When I called for help tha guy said " wait a minet let me go get that bow and see how its setup " . They are a class act and love to give good advise on how to get their products working for their customers . One of the freindlyest companies I' ve delt with .
