Having both, I'd say the Tropical will have a  little more flip (not really flip") on the backend (bit t will have  more of a true backend). It takes a good deal of oil on short pattern  with a LOT of very dry before the Slingshot's backend becomes even  moderate. By that time the Tropical is making a left turn.

 

That  said, the Tropical does have a solid option (it comes as either a Solid  or a Pearl, whereas the Slingshot only comes in a pearl, and drillings  could make both smoother, at the cost of slightly more overall hook.

 

If you're rev dominant, the SS is the way to go.  If you're speed dominant, the Tropical is better bet.

 

Personally,  being slightly rev dominant, and seeing slightly more oil these days,  I've begun using the Tropical Breeze Solid, drilled strong (pin in ring  finger). Previously I used the SS with the pin over the ring finger.
