My stock ION Reg was horrible.. I think they really are hit or miss.. Sometimes you get a good one and sometimes you get a bad one..
I think that the Torp is world's better and would perform better in the end..
And Yes, Clippard QEV's are diffenately the best.. LuckyPB sells the Clippard's with the Quick Disconnect for like 15 bucks..
