If the 400.s are shooting good from your grizzly then it must be a lot higher poundage than your Alaskan. On recurves you cant always follow the same rules for arrows as you do with a compound though.Your Alaskan is not center cut so it would need a arrow that can bend around the riser more to make up for that.If the 1916's dont quite shoot right then just try heavier or lighter points on it and they will work for you. If your Grizzly is say a 50# then a 2016 or 2018 would be about right in aluminum.For carbons there are a lot of people here that can give better advice than i can because i dont use carbon much. I dont know how much you know about trad hunting yet or if you have someone that is helping you where you live, but for trad bows we usually go more for heavier arrows and points than the compound crowd.Not the super fast flat trajectory thing so much but most of us dont shoot at deer over about 20 to 25 yards.You may be surprized though to find out that we get nice penitration with a 45 or 50 pound bow, often way more than most get with a 70 pound wheel bow.Its really two diffrent types of hunting, not any better than wheel bow shooters, just a diffrent way of going about it.One thing most of us like about trad is that its so simple.Ask plenty of questions in the pow wow section, you will get a lot of help there.
