I think you're just going to have to shoot the bow you want to shoot, and let the chips fall where they may. You've already done that, to some degree, by deciding you want to shoot a traditional bow rather than a compound bow, so this shouldn't be as hard a decision for you as someone deciding whether to shoot a 7 mm magnum or a 308.
The hard truth is that some bows do shoot better than other ones, by design, but another hard truth is that if you stick with the Chinook, you'll be shooting it a lot better a year from now than you are right now, and you'll be able to outshoot some folks shooting an ILF that haven't practiced as hard as you have.
