Your weight's for you man. You shouldn't let anyone else dictate it to you.
What I would suggest is putting on maybe 10 to 15 "trial pounds". Once you've gained that weight, take a week or so to feel it out (while not actively trying to gain more weight) and see how you like it.
If you find you like the new weight, I say go for it and put on however much more you feel like you'd want. If not, then 10-15 pounds shouldn't be too hard for you to shed.
