I've had a henderson 5 mil gold core hood for a while now. I actually thought it fit ok. I find it rather confining though. I bought a DUI suit last year and tried the hood on then - didn't like it at all. This year, my goldcore was lent out to someone, and i had to use the DUI. To my surprise, it was still a bit tight going on but once on, i didn't feel as confined as my goldcore. It actually feels quite nice on. I just didn't give it enought time last year. I'll be using it from now on. The goldcore is however almost perfectly dry inside of you dont let any water in. That can be a decent feature i'd think for some really cold dives.
