I've got a son that is 15yo 6' and 140lbs, I'm 180 and I'm also 46yo. I skied when I was in my 20s and always used whatever the boat owner threw at me and told me to put on but now we have a boat that can pull a skier (well soon we are almost ready to take it to the lake) I would like to get a pair of skies that I guess are combos double or slalom that would be good for him to learn and me to get out there on also, just for the fun not really in to tricks but just enjoying the ride on a summer day. So tips on what I should be looking for would be helpful. Just a good stable in-expensive pair. Also one of the things that threw me off was the lengths didn't know how long we should be looking at.
