Hmmmm. Reading trhough the lines it sounds like you will have the most fun on the Goliath and could easily use that for everything and love it. If you are set on keeping the BG (which it sounds like you are working with, but don't really love) then add the Whatever.
Would i be screwed if i went with et or airobic? Im looking for something with a really blunt tip, or better yet, capita shapeshifter.
