Thanks guys - testing is still in progress. I switched to MX2 so that I had a baseline to compare IX to so that I knew I had a good mount before spending 2 days running tests vs pump settings. I'm on the 3rd block out of 15 (5/15 done on IX). But if I'm on top of things I might be able to do 2 blocks a dayand then release the MX2 results. Then I can go back to IX and finish up
