I agree, rocket towers and el cheapo slo-mo thingies are the way to go. Dunno if unupgraded rockets are better than upgraded ones - damage is probably more valuable than range, as long as firing coverage is good. Also, to really maximise the score one should let some critters through - ideally the game would be finished with just one life left. Towers should always be purchased only after a wave is sent on its way to cash in on interest.

Must... stop... playing... hnngh...
