Love the thread, espeical like the Can do way you are approaching problems .
In regards to the bike shorts i will point out that it can be subjective , my skin can not handle nylon/polyester blends if i wear bike shorts made out of that you can bet your life i will have a rash in about an hour and if i ignore it i will be not wearing pants for a few days afterwards while i heal
.
Nylon/X or Polyester/X i can handle but never the two should meet in a sweaty environment . I had to learn this by trail and error ... and a embarrassing trip to the hospital
Keep up the riding mate
