hi magnolia, welcome to the buzz!
which saddle you're comfortable in depends so much on body type/size and climbing style that it's really hard to say. i'm 5'9" and 155 lbs with a fairly high center of gravity for a woman, and i want my saddle to be very "tweakable" (set-up options) and durable as it has to stand up to commercial tree work. the saddles i've liked best are buckingham's glide (heavy but built to last), edelrid's tree magic (super light, not quite as industrial strength), and treemagineer's tree motion (infinitely adjustable, very sturdy). all 3 have a sliding bridge, as the fixed attachment point saddles all chafe the hell out of my waste when i twist away from my tie-in. glide is probably the cheapest of the 3, and the easiest to find in the US. trying a bunch of saddles out is of course the best option, but not available to most of us.
good luck!
