Good Silent Partner harness?

I've been using the silent partner for a couple years now and absolutely love it. However, the tie-in loops on my current harness are a bit tight for everything the SP has me running through them and now that I'm in the market for a new harness, I wanted to see if anyone has knowledge of, or experience with any harnesses that offer larger tie-in loops?
I've seen the big-wall harnesses offering double belay loops but I can't tell if the tie-ins offer any more space. I should mention that I use the SP setup recommended in the manual, with 2 locking carabiners and the the end of the rope through my tie-in loops. On top of that, my gym requires a belayer, so I need to fit another rope through on those occasions. Recommendations?

Perfect! Anyone make an invisible rope?
