*Update* I had a nice conversation with Kyle Tucker (DSE) about this and he gave a nice recommendation for Turn One gear boxes, he told me that the owner Jeff and he were good friend and that he would take good care of me on a gear box. I talked with Jeff (Turn One) last night and my new box is on its way. Jeff was super helpful and provided several options and recommendations for my intentions. I was very pleased how he coached me along to identify exactly what I needed not necessarily what I thought I wanted, it was time well spent. I am getting a fresh (completely rebuilt) 12.7 box.
