I'm currently using an XPSC Rasa kit with 1/2" fittings and 7/16" tubing. Makes for a nice tight leak-proof connection, but is a pain to make changes on. Basically have to cut the ends off the tube. So I'd like to try compression fittings and smaller tubing. 3/8" or 1/4" tubing. And I have some questions. 1. What are the pros/cons of 1/4" tubing? 2. What are the pros/cons of compression fittings? 3. What are generally the best compression fittings? Bitspower? Thanks.
