All things being equal, I'd prefer a shouldered install myself. Also, if I were competing in benchrest I wouldn't bother. In the steel/field precision/prs stye shoots I do, the last bit of accuracy potential is rarely realized. If you have a high quality, inexpensive, fast local smith that'd change the equation as well.
We'll see how I feel about the system after a barrel or two, as for now I'm optimistic.
