You will break an antique bicycle frame before you break a blunt. SE being BMX oriented means their rims are likely explosion-proof.
I just got two pairs of the 36 hole SE J36U rims in the mail today. They are a little wider than the Blunt 35, but the profile is more round and the drilling offset from one hole to the next looks nicer than the Velocity in my opinion. Blunt 35s have a little flat spot around the inner circumference of the rim.

I took some measurements of stuff that I had on hand to get an idea of some of the widths of original singletube rims and their cross-sectional profile height. The entry for “44” is the SE rim.
