If you're going to go with a new pair definitely go with breathable. I'm not sure why Clint's bro' had problems but can assure you if you get a quality pair, they should not leak (if they do get them replaced!).
I've had them for 4+ years, and will do my best to not go back. I've stream fished them (and gotten almost to the top of my waders), float-tubed and kickboated without a problem. Occasionally they will spring a leak (like any waders) but since I got an Orvis pair I just bring them back to the shop and they replace them for free!
Lightweight, breathable, dry quickly and you can pack 'em up tight! No reason NOT to go with a breathable!
