@Agobran I think a senate would be a good choice. Best thing is to get out and ride a few for a few passes. Every ski will ride a bit different from person to person, so although all of the recommended skis are awesome, you might like some particular skis better. Earlier this year, I was pretty much deadset on buying a 2017 lithium senate, but after demoing the senate and vapor back to back, I liked the vapor 10x more.
As far as picking up damaged skis I would stay away from that, just cause you never know. There is a site http://discountwakeandski.com where I saw some pretty good deals on blemished graphics stuff.
