Ok, since you asked. On of my buddies that i work with picked up a swing a few weeks back, and after using it two days, went on vacation for a week. After some serious begging, some promises made, and some threats issued, he let me borrow it for the week. After probably close to fifty climbs here's my thoughts on it:
First off, i've been a pinnacle man for a long time and this is the first new saddle that i've given serious thought to replacing the pinnacle. But those upper d's are just too small. I hang too much crap off them and there is just not enough room. It is extremely comfortable, although it probably took about 15 climbs before it was dialed in and i was still messing with adjustments at the end of the week. And i am a big guy, this was probably one of the best fitting saddles i've worn-actually had to cinch it down. I wish the belt was a little more sturdier, the saw clips a bit heavier duty, and it came with suspenders (not sure if it's an available feature or not.) I also wasn't a huge fan of the batten adjustment-seemed kind of chintzy to me. I did like the extra two equipment loops on each side, could probably move the stuff off my d's to them if i went with this saddle.
My biggest adjustment problem was simply due to the fact that i'm used to a different setup on the lower d's on a pinnacle. I've always disliked bridges or saddles that i have to climb into. I started using the rings on the swing as i would the lower d's on my pinnacle (rope on one, split tail on the other to split the rope.) If it were my saddle, i'd get rid of the bridge and rings and put in maybe a teardrop biner on each side. Something that would allow me to bring that lower suspension point together when needed, but would allow me to separate them when i'm chunking. I did like the fact that the lower suspension points were up higher than on my pinnacle and made it feel like a second lanyard at the waist when chunking instead of a second lanyard half way down my thighs like the pinnacle does. Overall, very good saddle, just not my style.
(Sorry if there is any confusion-i can do it better than i can write about doing it.)
