That's pretty much why I got mine (from a member here, actually!).
I hate the "dead" feel of D-rings/full cheeks but Lacey (I assume due to her mouth issues) seems to do better when part of the bit's action is outside her mouth (the whole lateral action thing). So this bit was a compromise in that I got the loose ring I like and Lacey got the lateral action she likes.
So far (I jury-rigged some bit keepers out of rope) I've ridden in it twice and I really like it. Lacey also seems to like it. Perhaps not as much as she likes her ported curbs but she doesn't dislike it. She going much better in it than she's ever gone in any other kind of snaffle I've tried on her so I guess it's a win!
