I'm 205 on a good day, 210 on a bad day, 5'10". I asked for opinions on large vs medium on here and was pointed towards the large. I'm glad I did, it doesn't feel too big after you get it dialed in. I sat in the medium and it just felt too small for me after coming from a large Villain. At first I had trouble boofing it, but I just raised the seat a bit to get better contact inside the boat and pulled the seat all the way forward.
Don't let the 100+ gallons scare you, it doesn't feel that big and boat designers seem to be moving towards these large volume boats.
