Okay, if you look inside the yellow circle, you'll see something that is very different from the MII. The leg straps are TWO pieces of 2" webbing, compared to the one piece of 2" on the MII. This is a very good thing. Wider webbing means that the weight of your leg/body is distibuted over a wider area, duh! Basically, it a bit more comfy on the bottomside of the leg. Granted both saddles have adequate cushions to help distribute the load- the butterfly is making things nicer for us. If you look closely, the second piece of webbing is a sewn-on attachment that sits at an angle. It's ergonomic! It's like they planned it out and everything!
Ok, inside the blue circles you see something that in the rock climbing world I would refer to as either the butt strap or the comfort strap. These two straps do not serve add strength to the harness, but rather to keep the leg straps where you want them. You can tighten the straps down and have the leg straps ride really high so they crush you in places /forum/images/graemlins/frown.gif /forum/images/graemlins/frown.gif or you can loosen them a bit and have them sit wherever you'd like.
Now on the MII, there is one comfort strap per leg strap. In the Butterfly, there are two. I haven't noticed a difference yet, but my initial reaction is that it's too much. On my MII, that comfort strap tore when it got snagged on a branch one day when I swung from one limb to another (a swing further much further than I normally take and I tell you my heart about stopped when I heard the ripping sound /forum/images/graemlins/crazy.gif ) Anyway, when I got home that night, I cut off both the comfort straps and replaced them with a stouter webbing. I don't like messin' with my saddle when it may compromise the strength of it, but these are not strength/weight bearing components, so I cut them off and sewed new ones directly to the back pad. Point is, i will leave the 4 straps (2 on each leg) for a little while, then if I see them as extra, out come the scissors and warm up that Singer, because I will put just one, right where it's needed.
That's minor, though.
Finally, I like that the buckles on the leg straps are easier and faster to connect and disconnect that those on the MII. They are, to use MB's phrasing, the Cadillac of buckles. And something that Tom pointed out a while ago regarding the Glide saddle- these buckles are not pointy, thus friendly to the finger tips. And FWIW, the MII buckles aren't bad, but you do have to get used to them. These are perfect from the get-go.
Ok....what else.....
