Mostly I shoot CE Heritage 250's 30.5" long and woodmans on long adapters, with wrap and fletched, they are right at 550 grains. I do have a heavy arrow set up that I use a Heritage 350,100 grain brass inserts, 125 grain woodsman on a 125 grain steel adapter and it get me just over 750 grains and hits like a sledge hammer and flys like a dart. I haven't run across anything here in Iowa though, that is tough enough to need that setup yet. But if I ever get to chase an elk I think it would work very well.
My A&H is 64" 49#@28" and I have an extra set of limbs from O.L. that are 66" and 50#@28". I draw 29" and am setup with a clicker on pretty much everything I shoot now.
