L8, no problems. I glued up the glass first in the form, on the last piece of glass I left un sanded side up and had a piece of tape on it. Then when smooth on cured I pulled tape and sanded with 80 grit and glued on the Zebra wood pieces also in the form, I didn't have any springback and the riser is very stiff. I did extend the riser fade using a 24" powerlam made from actionboo it was 030 at the end of glass fade sanded to paper thin at end. Mass weight of riser feels great and I was able to cut shelf about 3/16" past center. Helen uses this bow for target shooting, indoor and outdoor..she just shot an outdoor 720 round and target distance was 70 meters.
