Reposting in the correct thread...grrrrr...

Do you have to stay a Rogue? You could just take that 1 die of SA and run with it. Get a nice 2hander, multiclass into a couple levels of Fighter, maybe splash in some Barbarian for pounce, hop into a PrC, and never look back. Use that 1 SA die to qualify for things like Craven and Staggering Strike for even more melee effectiveness, and Power Attack the bajebus out of things.

Besides, subtlety is overrated!
