Experience:
I've been a 1h + thrower for quite some time now. Putting wpf into 2 different places means automatically that you need lots of agility and weapon master and therefore will have less power strike. So for me, a masterwork long espada eslavona proved to be (nearly) useless. Swings glance on the heavy armor that most players wear and thrusts that in theory should make the sword extremely powerly didn't do as promised and glanced a lot as well.
Advice:
So my advice is this: If you're going for a strength build with a lot PS, you can safely pick a sword with a decent weapon length. But for agility builds, I'd pick a weapon with blunt or pierce on swings to get just a decent damage output. Don't worry about the short length of these weapons, your athletics should be quite able to guard you against kicks and you can quickly get into melee against backtracking long 2h and polearm users.
