I use:

Dart Monkey - Even in later rounds, actually. Lots of people don't use many Dart Monkeys or may even skip them altogether, but I love the ability to spam them out due to their inexpensiveness. I especially prefer Triple Darts when paired with a Bloon Impact, as that can take care of most kinds of Bloons (though I tend to buff at least my Bloon Impact with Camo Detection so as to get past Lead Camos)

Bomb Tower - As stated above, I tend to like using the Bloon Impact rather than the MOAB Mauler because by the time the MOABs come, I have enough power to stop them anyway. These are also incredibly effective in the later rounds (60+) whenever they send in storms of Ceramic Bloons.

Ice Tower - I agree with that, actually, though I tend to get Snap Freeze too, or at least Enhanced Freeze. Snap Freeze actually makes them really good offensive towers.

One more thing, Banana Farms were not recently buffed for this at all. You could be thinking of the path 2 tier 2 upgrade in which you can earn 50% more, which would indeed be $30.
