The second reason is that because the Kevlar has no stretch to it, once it loosens up a bit it just flops around in the stringbed doing nothing, so when you string it loose it feels great for a little while, then turns to crap. By stringing the entire bed tighter, it hangs in there a bit longer because it is tighter to begin with, and has the tighter cross to back it up.

I also find this true. Also, since I started playing again this is the first winter I've had kevlar since I was 18 many moons ago. Cold didn't seem to bother me then but tight kevlar and temps in the 40s-50s makes it very jarring. I say string lower as the temps drop. I've found the 18g to hold tension a little better than the 17g, which is very weird.

See this for other kevlar etc info. The 17g loses something like 28lbs of tension.
