It would be worth you looking into the new MauiFinCo. accesorie lines, There are 3 harnesses, Seat, Waist and a new Low Profile Waist.
These harnesses all come with a fixed bar, or sliding bar, Not two different harnesses, but on the same harness.
The look to be pretty well made, and the look awsome too

but this is just my two cents...
I used to have a patlove harness, wich i loved, But i cant remember to model. But it may not hurt tolookin to PL too.
