Black Apollo Bio-Fin Pros?

[mase]

I have an opportunity to pick up a pair of used Apollo Bio-Fin Pros in black for a great price.Any opinions would be appreciated. I do most of my diving in Tropical waters. I have a pair of Scubapro Twin speeds, which are OK but looking for something with a little bit more push.

I have used both and find the twin speeds to be more powerful than the bio fins.
