I've had a USIA bilam and a DUI TLS350 trilam that were light, dried quickly but tore easily on rocks and wrecks. The DUI leaked on 97 out of 100 dives. The Poseidon suit was heavier than my tanks and weights. The Diving Concepts suits and my current suit, a Waterproof have cordura and seem to be bullet-proof as far as climbing over rocks. I like the Waterproof for the seal replacement system. I can easily pop off a torn seal and replace it in less than a minute without glue. I had a DUI suit with ZipSeals but it was a hassle to get in the suit with dry gloves. With my Waterproof suit I use my old Diving Concepts rig system so I can just pop my gloves on and off without using wrist seals.
