The McDermott G-Core is a 13mm although it is not marketed as an "LD" shaft it is marketed as a "high performance" shaft but I have one and it deflects a lot less than a standard shaft, it is kind of the 1/2 way mark between the 2.

Looks like the OB XL and Classic XL just made it to store shelves... sucks I just ordered a Classic Pro, had this one been available a few days ago I might have given it a try since it would have made my order a little cheaper!![]()
