(and best friend) has the Henderson Gold Core 2 piece 7 mm wetsuit and he absolutely loves it. He swears that it is the best thing ever. He says that the lining makes it is real easy to put on, and it keeps him plenty warm. So far we haven't dove colder than 47 degrees, but he has never had a problem with the cold.
After he raved so much about the Gold Core, I replaced my Mares gloces with the Henderson Gold Core 5mm gloves, and they are easier to put on and to take off.
PS: the Henderson hood has a nice feature; a "valve" (for lack of a better word) that allows air to escape the hood, but not allow water to enter. I used one before I bought my custom suit and it worked very well.
My dos centavos, but only because you asked.
