Javaman said:One tricky thing about most (maybe all) Spyders is that is uses a mix of different threadings. If I remember right, the ASA is 1/8 NPT threaded which is the standard most paintball fittings and hoses use. Screwed into the ASA adapter is a 1/8" NPT - metric or standard (I can't remember which) adapter. The hose that is on the spyder won't work with the Palmer reg or any other standard fittings, it's threading is too coarse. You mentioned that you would need to buy a bottom line.... doesn't the compact come with one? If it does just remobe the thread adapter and use either a new SS hose or macrolines since you can't use the spyder one.
