different boat cloths are not uniformly convinced. Dynel is great when frictional wear is the problem (though is absorbs a lot of resin and is not that strong), but damage to paddle edges caused by *adults* involves not friction, but sharp, very localized compression force.
Carbon is great for compression force, but does not withstand frictional wear very well. Kevlar isn't very good with compression. The best available solution, on paper, is S-glass. Tougher than ordinary FG, very good in compression, very hard and so resists frictional wear well. Except that Dynel is "slippery", I don't know any way it is as good as S-glass.
Mitchell, one of the most experienced makers of advanced paddles, has settled on glass "rope" for paddle edging. They could have used Dynel.....
My Mitchell paddle has ash edging, and over 15+ years it has stood up quite well to local compression blows and to frictional wear. Lighter than glass or Dynel, and easily repaired.
I think Dynel paddle edging has gotten to be like Kevlar felt skid plates. Not used because it is best, but because it is kind of easy and has a good (undeserved) reputation for marketing.
