I've dove wet with a 7/5 henderson gold core with integrated hood, 7mil gold core boots and 7mil gold core golves with a pinnacle 3mil vest in 47deg water for about 35 minutes and was fine in the water. Its the surface interval that's tough and makes repetitive dives difficult. I now have a pinnacle freedom DS and love it. I got the DS, merino undergarment, rock boots, menino hood, and dry gloves for about $1400. That's about half the price for a DUI tls 350. I did a review on it recently so check my posts. I have not seen the pinnacle extreme for the prices discussed, but I do like the merino lining a lot. Its very warm. My pinnacle hood is menino lined and my head was not cold in 37deg water for 55 minutes! I would also recommend the freedom over the bare as they are nearly the same price and the pinnacle is a tri-lam compared to the bi-lam bare. The pinnacle also has suspenders and a thigh pocket standard.
