Yeah, you don't want something overwhelming, especially to beer drinkers with an unexpanded beer palate. Here are a couple options:
1) I'd definitely go with 320 over 300... don't want the banana/clove in the mix and make it too crazy (unless you're into that kinda thing
2) Try a nice American ale yeast. I've used US-05 with great success
3) Use a wit yeast!!! It'll produce some
banana/clove action but it will also produce some special esters and phenols that really belong in a wit. Try either WLP400, WLP410, or Wyeast #3944
Personally, I'd use the wit yeast to keep it style-appropriate. Well, hope this got to you before you head out to the LHBS. And whatever you choose, be sure to report back and GOOD LUCK!!!
