I tried both a long and short CP reg on my Protege, and the stock 360 reg was my choice.
The CPs were both extremely consistent over the chrono, at low BPS, say 1 BPS, but as the ROF went up, there was noticible shoot down, where the 360 would stay up and consistent as it was at lower BPS.
If it were me, I would start with the Vice with all stock parts (except maybe the board), and tune that for optimum, use it that way for a couple weeks, then swap in the part that you think will make the most difference, re-tune and try it for a couple weeks, etc. You'll find a combination of parts that you like most, which maybe just be the stock set-up.
