I don't know that much about NOS but I do know that generally if you're looking for 10's you don't want either a dry or wet setup you want a direct port setup... and that's gonna cost you some $$$'s. But if you're looking to reach 10's anyway you've got bigger problems than which nitrous setup you choose because the stock rearend is gonna give way before long.

) and reading what others have said, the 10 bolt is probably okay with NON-sticky tires (no drag radials, certainly no slicks) up to probably around 450 hp, then things start getting hairy. The weak point seems to be the differential cover. Aftermarket differential covers can be had for less than $200, that seems to help most people. Some have their cars in the 10's with just a built 10 bolt (mostly A4 guys), while others have broken their 10 bolt on their first pass stone stock. It's very touch and go. If you ultimately plan to build a 500+ hp car then you probably will just want to save time and get the 12 bolt now.
Honestly, if you are having a built driveline installed later, I would put a convertor behind it and spray the stock motor until it pops. I know a few guys spraying a 200shot on a relatively stock LS1 engine and they have been shocked at how much torture these motors can take...
