Re: Speed/Depth/Wind conundrum
Personally I'd go for the biggest plotter I could afford. The 8" Ray I have the most time on is pretty good but even bigger would be great (old eyes).
I'd have one about 14" if I could.
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
