Folks,
May I suggest that this all gets down to the perspective of the individual.
I naturally over sheet so I need leach tell tales to keep me in check.
However I have also sailed several seasons and done quite well with no tell tales at all.
When you have nothing the only indication you have is the feel of how the boat goes thru the water. At the end of the day that is what it is all about anyway.
I expect that both Rick and Randy have so much experience that they don't need to be told when they are overssheeting either because they don't do it or because it is bloody obvious to them so they don't need to be told.
I personally believe that our varying levels of experience give us different perspectives and so I think that if you are a beginner take a check on the leach tales ,if you have experience in the magnitude of Rick and Randy. Gedt rid of the distraction and focus on other important issues of trim.
jUST AS A PERSONAL OBSERVATION:-
i probably sail better without any tell trails but feel more secure when I have them to check. But is this sitiuation I relax and don;t continue to look for extra speed.
Just a personal observation!
