They were all a touch more stable (overstable...
) than my 9/10 180 CE QMS. As one would expect the lighters ones went a touch straighter and longer. I like the 172 and I played a round with just it today. Played a shorter wooded course trying to beat it up a bit and naturally it went too straight and didn't hit a lot of trees.
I beat in mercifully into a tree for 5 mins after the round and then it flew straighter. I like the slight extra D I get with it.
Mine are all kind of slick. I'm hoping the more I use it the grippier it will get. It's kind of hard too.
On a side note, the 1.2 SMS has a ton of dome. It's grippy and flies straight. D is about the same for me.
