Master Ambrose is so right on...
From the first board to the freshest boards I make for myself include a crispy new outline or template..why? because I can. I'll leave it up to my wandering eye do the copying. : )
I hear you Ambrose! What would surfing be if not for personal exploration and innovation? It is nice to be able to share though. To be able to draw your own outlines while incorporating others is a good thing. Ultimately, it comes down to what you do that matters. A great template guarantees nothing, but it sure can help.
A templet exchange is a great idea. It dosen't mean that you are copying someone elses work, its can be used as a starting point for something new. A curve here, a curve there and you may be one to something new. A bit of advice, someone sent me three outlines on one piece of paper, and all of the lines crossed at some point. Keep one outline to one side of the paper and another to the other side of the paper and make sure that the lines don't cross. Also roll the templets and send them in tubes and you won't have to deal with creases in the paper.
