As mentioned before, 35lbs is not always 35lbs - the type of the bow and "center cut" play an important role, too.
A bit of experimentation might be at hand. I used to get full length shafts, and shortened them until I got adequate results.
Surely one can easily adapt to left-right deviations. But excessive waving of unmatched spine will eat the arrow energy away, with an large drop over greater distance.
Tried my horsebow 35-40# cedar arrows (32", 70gn tip) last weekend with my hunting recurve (Samick Lightning, 30lbs), and the work fine (at least for me).
