Hi,
they didn't think Ti spokes would stand up over time. What they said was that they didn't think a rear wheel with Ti spokes was a good idea. This is just a guess, but 36 spokes might do the trick. Just don't expect it to last as long as
steel spokes would. I may yet do that for my wifes bike; but what she has is tie dyed Ti spokes; and they are $2.50 each. Multiply that by 36 and the result is ouch.
