spectrum:3. When I did take up scuba diving last year the the Arctic and companion vest were no brainers based on my 5mm suit and vest experieince.
4 Last fall I did get a drysuit and enjoyed diving through the winter. As we reach 50F I'll dust it off.
For my taste the drysuit is nice for when I need it but I much prefer the experieince of diving wet. Despite the matra of "once you dive dry you'll never want to dive wet" my experience (and that of many buddies) is that diving wet is more enjoyable.

I have the Velocity 5/4 and the Alpine Hooded 7MM. The Alpine has the same front zip as your Arctic. I considered the vest but went with the full suit after reading a number of posts re hooded suits vs. hooded vests.
I agree with your opinion on drysuits. I don't own one but I have done a number of "orientation" dives. I prefer diving wet, but I can see the appeal of the dry in bone chilling water. Most of the people I know that own them dive them all year around. This seems like a PITA to me in temperate water.
