I must have done something wrong last time I tried to post. I'm looking for some advice on which carbon express shaft size to use for a new bow. It's a 62" recurve pulling 63# at 29.5". I ordered the 250 shafts (at 31"), but they're much thinner than I'm used to. The 350's are what the chart says (and closer to the weight the bowyer recommended), but 3rivers advised 250. I've been shooting 23/64" wood shafts, which fly well, but since I got these 250's I'm all over the place. Something just doesn't feel right, so I'm wondering if I just have to get used to the smaller spine or should I get the 350's instead?
