this should be moved to the 'ski equipment' forums. you will get a lot more responses there. make a new post or hope a mod moves this soon. regarding your post, i really don't know anything about seths
That's a dumb response have you tried skiing a shorter ski, it's more maneuverable more fun easier to spin. I'm bigger than you and the only skis I have around 179 are powder skis.
I would say the 169 seths would be good for you if your skiing 70% BC and 30% park
They make a pretty good park ski. The width is nice on rails, they aren't too damn heavy, the flex isn't too stiff. They carve groomed snow fairly well. Of course they are sweet in powder. Really good all around. If I only had one ski for everything I'd probably go with Seth's, but if I was looking for park only they wouldn't be my frist choice.
