Thanks for all the responses. You all have given me a lot to consider.
As for Matt, it is a smaller version of Ultimate bluegill. I think it's 4". And it looks awesome. He posted pics on another forum. Don't think they are available yet, but it is definitely exciting.
This is what he said about them:
"My new little U2 (Ultimate 2) gills are 4in long and 2 in tall and they sit nose down on the bottom. If a fish knocks them over, they pop back up. They come in a flat tail and a swimming tail. These are more durrable then my previous gills and they are better balanced and run truer and swim better at all speeds."
Thanks again.
