I seem to have missed this thread earlier! We use Ultrasabers in our community ed classes (stunt model and padawan stunt model) and I have to say that after at least 15 classes with over 150 rabid young SW fans (mostly of the 8-12 year old boy variety), they've held up suprisingly well. We have had minor issues with a switch, and only recently an issue with a cap and filter tube coming unglued. This is after a year and a half of heavy use on 12 sabers. Neither the other instructor or I have had any issues with our own sabers. I did modify mine by adding weight to the hilt for better balance, but other than being more blade-heavy than I like (unavoidable), it's just fine. I'm considering sending them my MR Yoda to convert, as it has gaps in the blade.
You're right, Olos. I have already added some weight to the hilt, but as I am small to begin with, there is a point where I would simply not be able to wield the saber if I add enough weight to really balance the weight of the heavy-duty blade. I'm a bit spoiled because my costume sabers (non-electronic props) will accept a woven carbon-fibre blade that, in comparison to the Ultrasaber, really does feel weightless!
Remember, they are sabers. Not swords. Its OK to wield them with two hands, like in the original trilogy
on a more serious note, I find the blade weight to help with some motions... its not all bad to have a blade-heavy lightsaber, as long as you can use it to your benefits. Balance doesn't have to be perfect for you to perform.
