I went ahead and bought a pair of Versa Force shoes in my size (11/11.5) on sale at $65, just came in today, so to some degree at least I can answer my own question. I just walked briefly around in my house with a Versa Force on one foot and a virtually new Sun Dragon II on the other foot. The heel on the Versa Force feels decidedly higher. I'll go for a walk today in the Versa Force pair and see how this feels when I'm not getting a step-by-step comparison, but certainly my first reaction is to prefer what I'm used to, the Sun Dragon.
I also note that the toe box for the same size shoe seems about 1/8" narrower on the Versa Force. I'm keenly interested in this, as a wide toe box is what I particularly like Golite shoes for. It's hard to measure this accurately, but holding them side-by-side and measuring across the widest part of the toe box on both in the same way shows the difference, and at first glance it just looked a little narrower. I'm not sure if this will bother me or not, and unfortunately, a narrower shoe is something that only starts to bother me after quite a number of miles.
The mesh across the toe seems similar but not the same --- clearly it will breathe well. Unknown if it will rip out as fast. On each side of the shoe there's a little diagonal vent with what looks like literally fine wire mesh --- this will breathe and drain very well in this little spot, though as a drain hole IMO it's placed a bit high on the shoes. I can't help but compare to the little round drain holes lower down on Vietnam-era jungle boots.
If I have much more to say about these, I'll repeat the above and add to it in the gear review section of this site.
