I'm not a staffer, as that seems to concern some folks.
Received my Red Diamond about 2-3 weeks ago and had it drilled 50* x 4.5" x 45*.
Cover as came in box.
Have used on new Brunswick Synthetics a fresh THS and a broken down THS.
Getting thru the fronts is no problem and makes it move at 45' and hits like I expect a Lane Masters piece. Crack and never quits.
I'll more then likely buy another and drill 40* x 4" x 35* when there's a little more lane conditioner.
Overall extremely pleased and getting my Big Bang SE drilled shortly. Waiting on a few reviews from staffers to see what they think and what type of drilling's they have used.
Try a Lane Masters, you won't be sorry.
