Read my thread about my Omega thumbhole. I love the stock...except I am on the 2nd one and had it back to the company 3 times because the front sling stud was defective (it only held in by 2 thread turns in an oversized hole...they put a nut on back the 1st time, but cracked the stock so I sent it back 2nd time, the new stock pulled out like the first, so they repaired it right the 3rd time around).
I love the accuracy and cleaning ease, though I had to bed it to get best accuracy. It is really fussy about bullets too. I'd get a Disc Elite, but I refuse to be tied into their Disc system.
