In BTD6, Monkey Bank. 2/3/0 is best crosspath. Personally would start off with 2/0/0 to get some extra early income quickly and then 2/3/0 to get the Bank upgrade. Lots of 2/3/0 Banks is great. You could also use 4/2/0 Banana Research Facilities too, but you'll need some decent hand micro in order to collect those crates so regularly.
