About the basket-hilt, yes you're probably right that they are too powerful combared to other things. And yes, they cannot be used with two-handed swords, however.... my head tells me that I've seen an image of a basket-hilted dagger once. I might be wrong, but my minds eye certainly insists upon that
-1 goal due to bulkiness also makes much sense, even if one only applies one of the indicated basket-hilt effects. I don't know... The next time we get the chance of making a FS rule system, which I hope won't happen for at least a decade (because it is MUCH more fun concentrating on setting content and dramas), we'll have to do playtesting and perhaps even an open source style of mechanics development...
