It wasn't available, so I don't have one. Maybe next season. I hope it allows more flex for SL riding than my non-spring "soft" GS plate does. I see people riding non-spring plates on SL boards in World Cup and I literally do not know how they do it. I tried mine on my F2 Proto SL and could not bend it. Or at least not consistently. One out of maybe ten carves I would hit the g-spot and the board would carve. Otherwise, I hated it. I love it on my GS board though.
Seems like about half the world cup field are using spring plates, like Benjamin Karl and Stefan Baumeister to name a few. I like their riding and they are successful. The spring plate I had briefly before I sold it to my athlete was great and I could make it work well. Very powerful, gobs of edge hold, but heavy.
