Hi big E. I have a 2013 chest zip 3-2mm flash bomb. While the fit was great, I only rated it about maybe 7.5 out of 10 due to stretch when paddling. ie it makes you tired when paddling in strong currents. I was in a rip curl outlet store in USA recently and tried on all the latest 2015 wetsuits. With zipperless I think they work best in either 2-2 or to lesser extent 3-2 in as far as getting into them and that was with both suit and I dry in store. I ended up purchasing a 2015 chest zip flash bomb in 2-2. I absolutely love it, and is so much flexier than the old flash bombs. I found it warmer due to the flex material hugs you more. The neck is greatly improved and much more comfortable. I have used it surfing in 16-17 degrees water over in the states and it was all I needed especially when the sun was out the chest panel really heats up, and flash material gets hot. Great suit 9.5 out of 10 only losing .5 as I'm unsure of durability. Best part it was only $229 USD. A suit is only as good as it's fit I would never buy with out trying first no matter how much you pay. If I were you I'd look at a CZ F-B 3-2 as a starting point. Make sure it's the newer 2015. Hope something there helps.
