RE: Tectonic for isonic
Looking back to my earlier post above, I don't think I was as clear as I would have hoped. In the final paragraph, it might appear that I put Ian in a position to recommend a Tectonics fin. While, that would apply to my personal recommendations, I wouldn't necessarily think those constraints would apply to his feelings or recommendations. The optimum brands and appropriate sizes would be his choice. Yet overall, I don't think that the size ranges I that thought pertinent here are out of the ballpark.
