10gen...----I ended up getting the 2b and I'm glad i did. The difference I could see between the bartlien 2b and their 3 was that the 2b just tappered faster. I would make your decision between a 2b and a 3 based more on if you planned to thread the barrel. If not and you are looking for lighter, id go 2b. Its very similar to a rock 3 as far as i can read. Thanks to photofcket its almost impossible to look through old threads. The 2b appears to be very similar to what you would see on a weatherby accumark. If your going to flute I would go with their 3 and flute it, gaining rigidity and no weight....
Just my opinion.

Thanks for the help all!
