Improving Bloons TD Defense Setups

Hi everyone,

I’m curious about how you all approach bloons td defense . I tend to overinvest in a few powerful towers, but sometimes I get caught off guard by certain rounds.

Do you recommend spreading out defenses across different tower types, or is it better to specialize in just a couple and upgrade heavily? I’d love to learn about defensive setups that hold strong under pressure, especially during late-game waves when things get hectic. Any suggestions or examples would be appreciated.
