I've almost exclusively made arrows from bamboo with 100-125gr points. They usually weigh in the 400gr +-50 range with about 40# spine. Since all my bows are in the 40-45# range they shoot pretty well. Over the last couple of years I've accumulated quite a bunch of lower spine shafts that are just sitting in the corner. It finally occurred to me that if I use a lighter point these may be stiff enough and also be a much lighter arrow. I made a couple, one with a 50gr point and one with an Ocean Spray foreshaft and no point. I figured the OS would be heavy enough by itself. They seemed to bareshaft nicely but after I fletched them they seemed to hit all over the place from 20yds. The balance point is about an inch forward of center. Is there something else I should be doing? These are target only but maybe some flight arrow tech might be in order?
