Shewie - Thanks, let me know once you've decided on a date for your trip and your likely route; I'll see if I can meet you on your way down.
Totumpole - a WBBB is a Warbonnet Black Bird Hammock. If you ever get into hammocking, you'll want one!!
Mat - Thanks for the info, I'd heard that Brandon had shortened the RL from 100" to 98" and that a tighter RL seemed to sort the problem out for most people. Funny though that Shewie has found a slacker RL to be better. Everyone is different I suppose, thats why I'd like to give it a quick try.
I've heard the calf ridge is there on a lot of hammocks, not just the WB. My DD has a tight ridge down the middle which could put pressure on my calf if I hung my feet on the slacker fabric. Perhaps the footbox on the WBBB just makes this a bit more obvious.
Thanks
Mark
