Kraton, I'm a little embarrassed to admit to this in public[&o], but my Patriot is also tuned and shooting very well with the nock point below center. I'm not sure what, how or why and I got real tired trying to figure it out so I just went with what it wanted.
I'm about 1/8" below center at the middle of my string loop.
TodayI put a Phantom, Stinger and Slicktrick inside of 1" from point of aim at 30 yards. (2" groups if you want to look at it that way). And they are shooting w/ my fieldtips.

I'm sure someone with more tuning know how could figure this out, but season is coming on too fast for me to worry about it much more.

My bare shafts are flying like darts and if anything hit a little high. (I always fling one with my3 fletchedshotgroup)

If you put your back to normal do your slicktricks still hit with your fieldpoint? if so, forget the bare shafts- tune for the broadheads.
I'd be more concerned about straight and true arrow flight than how my bare shafts shot.
The slicktrick website has a good paragraph or two concerning this line of thinking. Straight flying arrows carry more energy and allow the arrow to penetrate much better.
