Took some work to convince my better half that I could hang in my office (spare bedroom) without bringing down the house. Now that I'm no longer in steerage, I decided to go with a brazilian. Much easier to use indoors since it's long and hangs at a steep angle. With the gathered end I needed over 20' btw hang points on the basement joists but the brazilian needs only 15' and since the hang angle is around 45deg, the load is less than body weight.
