You'd get about 265 fps with the 60# Kobalt at 340gr, 27.5" draw. It's not a good idea to twist/untwist your bow string. You can fudge with it a little but all you're doing is changing the length of the string that was intended for your bow after a certian point, you'll end upchanging the poundage of the bow and losingbow camefficiency, counter productive to what you're trying to do in the first place.

If you're on a budget, get a used one, there are lots of really great bows that you can pick up for about half of what it cost new just one year later. Many guys trade upevery year for the latest and greatest and that leaves some bargins out there.
