Bag over axle is probably the easiest way to ensure a long lasting, dependable system. I wouldn't personally run a double convoluted bag tho, the sleeve bags will offer a better ride when not towing.
JUSTIN- I would not suggest using a 2-link on a tow vehicle. I too have seen many people run them, but there are other issues that can arise from using them. The stability that is offered by a system that does not allow the truck to sway is nice, but there are better ways to achieve that without compromising your suspension design.
