Kosovo just when I think I had it figured out. I was looking at a warbonnet BB. I thought a adjustable ridge line was the way to go so I could get it just right and forget about it. Wen I emailed warbonnet this is what they told me.
"our ridgeline does not adjust and i don't recommend modifying it to be adjustable, it's set fixed to the length of the bugnetting, as far as comfort goes it's the many other factors in how you have it hung that make the difference in comfort, having the head end lower, sleeping more toward the head end ect. changing the ridgeline length will do little for you"
So now I'm really confused. I've heard and read that WBBB is really comfortable so maybe I shouldn't worry so much.
