There are a few really big hogs that are using the wallows we'll be hunting. Most we've seen and shot have been from 150-225 pounds, but last fall my buddy had a massive boar come in on him, but he couldn't get a shot at it. He said it had to be well over 300#. I trust his judgement, too. He's a published biologist and not prone to exaggerating.
Carbon-wise, I have some AD Trad Lights that shoot well out of it with a total weight of around 550. That's about as heavy as I can go with this bow and those arrows. I do have room to cut them down another inch, so I might be able to get the weight up to 570.
I also get good flight with some gt 5575s at around 600 grains (I think). I haven't spent much time fiddling with those shafts.
The AD Hammerheads I have are too stiff, unless I get stupid heavy with them. They fly well at a total of 880 grains, but man are they slow. My eye is attuned to a much flatter flight. I've also got some 7595s, but I'd need 400 grains up front on them for around 800 grains total. Those heavy arrows really rock a target.
Rob, you could be right about the weight. It does, however, feel a lot lighter than other 55@28 bows I've got. Of course, the others are shorter r/d bows and have a totally different feel to them.
I'll probably end up using the Surewoods. They are just such a tough shaft.
