I use to like the billabong wetsuits solution gold. They were great wetsuits but overtime they would come apart a little bit. I still like like them but i converted over to the Xcel Infiniti Drylock. I only use a 3/2 and 4/3 drylock all year and they're great.
Are you using the hooded 4/3? Reason i ask is this is my second winter in a 5/4 Xcel Inifititi drylock and i kind of wish i had gone with the hooded 4/3 cause the 5/4 is borderline too warm most of the time on the delmarva even now with the 40 degree water its more than warm enough.
