I have the big bird problem as well 6'1+ @ 160, size 12 shoe and have tried a number of suits on and here is what I've found in my quest to buy a new suit
Back entry, I had a old scuba pro M/L vulancized style suit and had no problem with the lengrh issue. Since we don't stretch it horizontally, we have a bit more play vertically.
Back entries have a bit more flexibilty in this area I believe. The only problem I had was since I am so thin, the excess material created a fair amount of drag.
I also tried the Bare HD M/L and it was just a wee to short in the upper torso. However when I had the boots changed to neo-socks, you can get the length extended just enough to deal with this. I wanted to avoid the Large/Tall as it would leave too much slack material and cause more drag in the water.
The Bare line has a Medium Tall, Medium Large Tall and Large Tall. IMHO the measurements are close but I think they are a bit on the conservative side and cater more for people with larger builds. You seem like a good canditate for the medium tall in the Bare line either trilam or neo. If you are expecting a spare tire anytime soon, you could get the MLT and since you will likely have the boots changed, they can give an inch or so to address the length (unless your are all torso and no legs
THere are some other things to consider as well, is this purely rec or are you thinking tech as well? If tech, you may want the neoprene since is it more puncture resistant and will be more of a tight fit. This will give you more freedom of movement and less material to get caught on objects.
