I shoot a thunderbird thats 48@28 and I shoot 1916's with a 200gr point,,, sounds light but they bareshaft tune perfect! I'd say with yours you can go with the 2016's for a decent mass weight or lighten it with 2114's but depends on what you like.
Pm me if you don't find any forsale but Ed's correct where you can get them there,,, also if you plan on shooting any of those fat hogs down in Alabama I'd try some 2018's with 250-300 grain points to have a heavier arrow...
are you near Lilian, Alabama by the way?
