Hey Robin did some research for ya. First off, I noticed that you said your arrows where 27 inches long and that your draw lenght was 26.5. If you don' t have a arrow rest that is a overdraw style you need to get one. You should be able to shoot 24.5 to 25.5 inch arrows with no problem. Here we go, all these arrows were figured at 25 inch arrow length, 50lb draw and your draw lenght. Easton ACC 2L-18 hyperspeeds with rps inserts, 60 grain easton screw-in points, easton G-nock & insert, and bi-delta 4 inch vanes (only weigh 7.9 gr. per inch). The entire arrow will weigh 252 grains and have a F.O.C. of 7.9 %. Second we have the Carbon Express 3D selects or the CX 100s with the rps inserts weighing 12 gr., the Easton 60 gr. screw-in point, their nock at 8 gr., and the 4inch Bi-delta vanes you get a 259gr. arrow with a 7.4% F.O.C. Lastly there is the Carbon Express CXL 150s. These shafts are bigger in diameter than the others I listed (about the size of a 2312 shaft) so they might grab you a few lines, but they weigh a little more. These shafts have a rps insert that weighs 28gr, the nock is 10.3gr, easton 50gr screw-in point, and using the 4 inch Bi-delta vanes you get a arrow that weighs 267gr with a 7.8% F.O.C. Now as far as the string goes I would have to say that the Winners Choice strings are the way to go based on what other people have told me. They use pre-stretched 8125 material. I make my own out of BCY 452 which is a no stretch material ( minus a couple of stands due to being slower than 8125). The Winners Choice strings are pricey though, around $100. Some one else might be able to direct you to someone who makes a similar string cheaper. Lastly, let me steer you toward Lancaster Archery. They have a excellant on-line store and a great technical back-up service, they are great to deal with. Their site is at www.lancasterarchery.com. Hope this helps.[8D][8D][8D]
