If you're going to be doing wreck diving out of the Boston area you're going to be in diving heaven. But if you are very serious, and especially serious about doing nearly year-round diving, then scrap the 7mm wetsuit and go for a good drysuit. This would almost be essential for wreck diving, and it would also drop the amount of weight you would carry (if it's a trilaminate or compressed neoprene drysuit). Also, I would seriously consider a SS backplate/wing--and if you're diving a steel tank you would then need to carry very little and possibly even no weight (for some of the better and deeper wreck diving in NE you likely won't be diving an aluminum 80). The Transpac/Venture wing would also work, but once you move into a larger tank I think you would find a backplate much more stable and comfortable. The 30lb of lift of the Venture wing would be enough, especially if you're diving a drysuit, but in very cold and rougher seas you might appreciate something a bit more robust, if not with a bit more lift as well--esp if you begin carrying lots of stuff down there (lights, reels, etc.)--but technically 30lbs of lift would work (but maybe not if you persist with a 7mm wetsuit and have to carry close to 30lbs of weight). Keep in mind as well that with most operators you will need a side mount or pony tank for deeper wreck diving.
