If you do a lot of body thrusting, which requires a lot of arm strength which you probaly already have, try single line footlocking.
Get your TIP as you normally would, only don't get your rope right next to the main stem, just out away from it a little ways. Set up your climbing hitch with pulley to mind the slack. Then just pull yourself up the rope and FL the tail with your feet to take up the slack. Once you get a feel on how to get a bite on the rope with your feet, you can alternate between your arms and your legs. I guarantee you will never go back to body thrusting which is much more exhausting on the body, especially the arms.
Single line FL isn't as fast as Dbl. line but there are are pro's and con's to both methods. Single line works best about mid- way between the ground and your tie in point. You have to deal with the stretch in the rope when you start out. If I use this method I take a couple pulls on the rope then start to FL.
I'm Right over Left if any one is keeping score.
