I agree with the uncut steering tube suggestion. I like my bars as high as possible to relieve the folding at the waist.
I am a Clydesdale at 6'1 and 270 pounds. So depending on your wheel set up, I do use 32 spoke 30 mm deep rims.
Do find a GOOD wheelbuilder to build your wheels. I build my own after having so many problems with local bike shop guys who call themselves pros when they are not. Not even close!
I gave these wheels to a buddy who was in need but not till after I put over 10,000 miles on them. The story of these wheels:
They came on my new bike back in 1998. They would not stay true (straight) for more than 100 miles. Bike shop pros said I was too heavy back then at 220 pounds. 3 trips withing 2 weeks to the shop, they sucked! Would not stay true so I ended up going to another guy I know who builds wheels. He built a set of Velocity Deep V wheels for me with 32 spokes. They were rock solid for years.
Had more problems with more bike purchases. So I decided to build wheels myself. I built my first wheel and it was great while I paid attention to every detail possible. I had great success so I dug these wheels out of my closet and thought I might give it a try building them myself.
I used the same exact parts, same rims, same spokes, I stripped everything down to pieces. I built the wheels back up and VOILA!!!! Perfectly good set of wheel with 28back/24front spoke wheels.
Like I said, I put over 10,000 miles on them with ZERO problems so it can be done depending on the skill of the wheel builder you chose.
I have since then built wheels for all my bikes, 7 bikes and probably 15 wheels. All with no issues but I did use 32 on most but a couple sets with 28 front and rear spokes to be safe. Not one wheel with an issue.
So imo, if you use a 28 spoke rear wheel, you will be ok if the builder does a good job. Not knowing how much you weigh either, 210 pounds is not all that much figuring I was riding the 28 spokes anywhere from 220-270 pounds over 10 years. You don't state your weight.
Loved this bike and these wheels. Sadly THE FRAME broke and the wheels are still perfect.
I did a ton of climbing on these wheels so they weren't babied and they are fine. Miss the frame though.
