Welcome to the forum.
I'm in the SC upstate as well.
I have the WBBB 1.7 double and have never regretted it. I use the MacCat Deluxe or MacCat Ultra with doors depending on the temps and weather expected.
We have a group hang planned at Devil's Fork on Lake Jocassee in October.
Check it out. You'll get to see a lot of different setups and gear.
