RAH I would most definitely use SFS in your pond. I've posted my impressions before about them and they present almost no downside that I can think of.
The main struggle is sourcing them. I was unable to dedicate enough time and energy (and find suitable equipment or build it) that would allow me to harvest or trap, or net large enough quantities to share with others. But it is back on my list of things to do again this year.
You are fortunate if they are native in your streams or lakes already. I'm not sure there are any natively in the bodies of water in SW michigan. The fish database page that was linked to in a thread earlier has a few pictures and entries for SFS by me but the pictures listed makes me real skeptical about the identification accuracy.
Bill has a great write up about them too.
