The string at rest does not touch the rail. It does not move, but there is a gap. It is a top release pawl, so once it lets loose it settles into place. I shot it with both flat and moon nocks and noticed no diferance in accuracy so that tells me that the serving is square on the flat nock so rollover is not an issue. Fit and finish is very good. There are a few seams on the stock that I noticed, but they are actually carved into the stock so it is not slick.
I have a review I did on Archery Talk on the bows I saw at the ATA show. If you all would like I will copy it and post it here....let me know.
Keep in mind that these are still my opinions

your milage may vary....
