My character, who used a large fullblade (he was a human with a resizing blade and a magic item that gave him monkey grip) got around it by getting a weapon storage enchantment put on his gloves so he didn't need a sheath, he just snapped his fingers and BAM! huge sword. Combined with some backup weapons, he was quite effective. Granted, he was a cleric/prestige paladin, so of course he was effective, but it's pretty much an ideal way to handle things if you have the cash. (my character managed to get a hold of the entire party's big loot reward, so he had the wealth of an ECL16 at ECL 10. And again, paladin, so it was on accident)
