I agree with trying the cheaper route first. The Mustang sits me lower and about an inch or so back. Even with the MBLs, I am now "reaching" for a comfortable arm/shoulder position and am unable to sit back in the pocket of the seat. I have had lower back surgery already, and have a few protruding disks in my neck (occupational hazard). I need to be fully upright with a relaxed arm position. I hope the Helibars do the trick...
