Every time you add an improvement, it makes it a bit easier to use. Every single step, from larger heavier risers, to cut to center, to stabilizers to front sight, rear sight, range finder, release, all these. MOST folks SHOULD be able to shoot a rifle easier and more accurately than a longbow.
That does not mean you cannot shoot a longbow, and very accurately at that. You need to play with it and practice with it and find what works best for you. Often we are stuck on a certain form, hold, draw etc and think that is the best for all bows and all situations. Often it is not.
Don't compare your longbow against any other bow. It is what it is, learn how to use IT, if you really want to use it.
My pick up truck isn't as good handling as a sports car (though it is pretty danged fast), not as comfy as a Cadillac, but boy, when it comes to hauling a ton of crap ( maybe literally), those others won't touch it. It is what it is, use it for what it is.
There is a shoot at Horicon this weekend. You should come on out and ask questions in person so we can try to help. Bring your longbow.
