I have a Carbon Express Predator shaft, full length, .600 spine (20-40lbs). The shaft is full length (30") and it weighs 252 grains on a digital scale, WITH a nock and insert. (no fletching) These shafts weigh 7.7 grains per inch.
Cut at 26", fletched with three short feathers, and a 90 grain tip, I think you will still end up with an arrow just over 10gpp.
My son shoots these arrows cut at 28" with a 175 grain tip drawing 40 lbs@ 27" and gets GREAT flight from them off the shelf and centershot. His arrows end up just under 11gpp.
I`m afraid that if you cut even these carbons to 26" they may end up too stiff for 32 lbs. Especially with a light tip.
I get these shafts from a local store and pay too much for them trying to help him out. I`m not sure if any of the sponsors here carry them or not.
These are the best shafts for low draw weight I have found yet. Because of her draw weight it will be tough to end up under 11gpp. But, the difference between 9gpp and 11gpp is not very noticeable.
Hope this helps.
