If you're fit, and your BP is normal, I would say to not worry about weight. If you're worried about the way you look, you might "feel" better if you lose weight, but it sounds like you're in good shape, and I'd say don't worry about it. You could probably school plenty of 150 pounders on the bike I'm sure.
Just keep riding and stay in shape. I've found it makes exercising harder when I obsess about my weight. If I exercise for fitness, and for training for races and stuff, I find it more enjoyable, and I still lose weight.
BTW, "The Historian", those pictures are amazing. I think the most telling thing in the pictures is the fact that you look so much happier when you're active and stuff. Good on ya. I love to see pics like that. I think it's amazing what people are capable of when they set their minds to things. Congrats again.
