I haven't used the Boomerang Thrower as often as other towers, especially the Buccaneer, Ninja, Druid, Super Monkey, Spike Factory, Village. But I'll get there real soon.

In the meantime, I did test the quality of the Improved Rangs and Glaives upgrades and felt they are good. The Faster Rangs upgrade helps a lot too, especially higher upgrades. And the Ricochet upgrade is solid and useful for its purpose of shredding down many Grouped Bloons down into more manageable parts. As for other upgrades, I find the Kylie Boomerang interesting in theory, but I'll test it out later.
