While researching the sirius riser on another forum I found that Lancaster Archery had a rh victor riser on sale for $29.99 so I ordered one. Got my victor riser this morning and put my 50# sage limbs on it. They fit perfect and bolt right in. I only had a string that was 1" too long so the brace height is too low. It appears to make a 66" to 67" bow. Had to run so only did a quick FD curve and will build a new string tomorrow and get a new FD curve and if its clear I'll shoot it through the chrono. I may have found a way to get rid of these sage limbs. Wish they would have had a left handed one because the limb pad angle would work with my longbow limbs
Here's a picture of the riser from lancaster its a 24" riser and a picture of the fd curve which I will redo once I have time to build a shorter string.
