Which Karsten cheek piece?

[tacticalpanda]

I am looking to buy a Karsten cheek peice. I know I want either "B" or "C" due to having a Triad Stock pack that I want to mount. Also switching heights after its set isn't going to happen so I don't think I need "A". I was wondering if anyone has a preference to either the B or C model and why?

I have 1 A model and 2 B models. I like the B better and one reason is you have to lower or take the cheek piece off to clean the bolt rifle, unless you take the action out of the stock. The A model that I got came on a used HS Precision stock, and it was a pain to get it set the same again, so I swapped it with the B that I put on my M1A and it works good on that, because you clean it from the front. The holes on the B model make it easy to reset the height after cleaning the rifle. I really like the cheek piece.
