I've been reviewing sound fonts on my son's Prophecy with a 36" UEHG blade, and I find the weight is off, at least from what I'm used to on the Bellicose's heavier hilt. For me, it would work like that that, but I'm not used to the weight difference at all.
When a 36" UEMG blade is put in, the weight is awesome and the Prophecy feels like a fencing foil. I haven't yet tried a 32" blade as I don't own one, but it shouldn't be TOO much different from the 36" UEMG.
40 is more than pushing it...
And I usually use UEMG so that's good.
