Fritz GoldTip Ultralight Series 22. they are slightly larger diameter than the Xt 7595 and weigh in at 7.3 gr per inch, you lose some of this with heavier inserts, and nock adapters(lighter than the lock nocks) needed for this shaft but with these component installed my 29" shafts weigh 261 grains without points or fletching. Also they are a little stiffer than the 7595 but should still tune very well out of your setup.
