I have the same front stand as you and faced the same quandary. I ended up taking the largest one to work (machine shop) and turning it down to .968" (24.6MM) When using the 22MM pin it seems that during the first bit of lift, there’s quite a bit of pressure on the top edge of the pin where it interfaces with the inner bore of the steering tube. Is it enough to cause distortion? I don't know, but didn't want to take the chance.
One more thing,....it seems that when beginning the lift the lower part of the "bridge" on the stand would scrape the fender if I didn't assist a bit. Be careful, or remove the fender first. And be sure the bike is supported with a rear stand first (you may have known that, but just in case).
