One of my biggest issues is creating a good setup while still getting lots of cash.

Let me explain.

My biggest moneymaker is FP with Banana Replicator and King of Ooo scepter. I put her at the front, and make sure she has a low damage high pierce/speed setup so she can tag all the bloons, maximizing gold income. However, this really messes up my defense, since I have to put all my other towers further back so that they don't pop all the bloons first, making me lose that income. It might not seem that bad at first, but it hurts my defense because I can't put allies in range for Royal Fury, can't get good placements, can't upgrade to MAF on CMD Cassie or place down Finn with Missile trinket, etc. until I have the necessary amount of money to buy the rest of my defense. That usually means I need to save up until ≈ 150000 dollars, which takes until mid-60s, and even then, I have to stick with a pretty bad layout.

Do you guys have any advice for reaching those amounts of money without doing this? I recently got Dr. Monkey, and his Alchemy upgrade has been super helpful, but even then, it's not enough, especially since I need to put him in range of my support towers to maximize his potential.
