D97 or D10 seems to be much preferred over Fast Flight these days, all are different versions of the newer low stretch string materials. Pretty much everyone that tries them prefers the low stretch material to dacron.

With your arrows, I would suggest trying some heavier points, like 125 and 160 gr, with your 2114's. A 2114 seems a bit stiff to me for 45 lb and the heavier points will lower the dynamic spine.
