So much depends on recipe, execution, aging, etc. that it's hard to say what the problem could be. I can tell right off the bat that 2 weeks on a OG heavy clone like Raging Bitch deserves way more time in primary, but I think you've reached that point where your brew method just needs some refining, so some questions:
-What's your water quality like where you live? Do you use filtered water to top off or tap water?
-Do you make your own recipes or pull them from online/friend sources?
-How's your ingredient quality? i.e. do you buy from LHBS per recipe or do you have back-stock of malts, hops, etc. at home?
-Do you monitor boil & fermentation temps? (Note: you should.
-Do you use yeast starters?
-How's your bottling process? Do you sanitize religiously? Mix the proper amount of priming sugar & blend it evenly into the brew?
