OK, I have read up on making the Spyder LP. I have an Xtra with E grip. I need to know what Reg to get and whether to get a valve or not. I hear about 32 degrees valves used but cant find them for sale. Also, is there anything else. I use HPA, not Co2. But, would be nice if I could use both if I wanted. My tank runs at 800 PSI. Any info will help. Thanks.
