Hmm, they look a little uncomfortable, but functional. Would they even be that heavy with the mounts and sliders. The seats are 18.7lbs each, sliders are like 1lb, and mounts can't be too heavy? I'd guess about 25lbs but then again I don't know. I like the Fighter's looks, but they're more expensive. Quick fit's are the way to go for harnesses. Let us know what you decide on
