Hey all, I just wanted some input from y'all experienced in building bikes.

I'm in the process of getting a steel (TIG-welded, straight gauge 0.9mm 4130 tubing) bike built for my 6'7" body, by Gene Spicer from Indiana.

It's going to be my new all-around bike, for commuting most of all, but also for 50+mile rides on weekends and and getting groceries and such. I don't have a car, and I currently ride a ~62cm Schwinn World Sport from 1985. It definitely doesn't fit me, but I've dealt with it the best I could.

Based on my measurements:
-37.75" inseam
-78.75" total height
-15.5" forearm
-28.375" full arm length

I am getting a bike with:
-36.5" standover
-66 or 67cm seat tube (c-t)
-63cm top tube
-73 degree head tube
-74 degree seat tube
-310mm BB height
-270mm head tube
-420mm chainstay


I just think I want some feedback from other builders who have maybe built for tall folks like myself. Do these dimensions seem right? I've used a few online fit calculators and got results similar to what is above, but I'm just scared that it will be too big, or feel super wobbly under me. I know I will probably feel stretched out at first, but will end up realizing it's just comfortable.

Here are a couple pictures of my current bike for comparison.

It's got:
-61cm seat tube (c-c)
-63cm seat tube (c-t)
-57cm top tube
-130mm stem
-200mm headtube
-280mm BB height

I hate my saddle to handlebar drop, it's incredibly far for comfort, but a taller stem, even 140mm, feels weird as it cramps my arms even closer to my torso. I pretty much only ride on the flats now anyway, because of this problem.
