I went through this last spring, I went with Goodyear MTR's. They made a huge difference on my cruisers highway habits and they are a lot nicer all around than the Swampers I was running.
They balanced well, and they are wearing really well. They have an extra sidewall ply over the BFG's if I remember correctly.
I am very happy with my tires... FWIW, I bought them from Summit Racing and had them shipped for only 5 bucks each... no tax. Sweet deal.
