Thanks Clay - he probably only guides for SMALLmouth and LARGEmouth bass right?

No-Tye - The programs you referenced will be VERY helpful. However I'm still looking for a way to determine what size a guide is. Example, I have some leftover guides laying around loose and in different sizes. How do I determine what size they are? I'm hoping there's a chart available somewhere.

I suppose I could order some guides in different sizes (they're not too expensive) and just keep them as reference but I was hoping there was another way.
