Keep going man, I love UMSv2. My monthly payment are four times higher now after I started the subs, the subs paid itself. I use for two cycle IIRC, use stage 4 for some month before going to X4A. Shannon said it's a good thing to change subs once in a while to let off the 'pressure' that bombarded us especially with multistage program like UMSv2. All in all, good luck, in six month there's possibility that I'm using UMSv2 again, for now, I'm gonna use the sticky speedboat X4A offer.
