I've had many skis that I have taken to Jay and gotten to try, but Jay isn't anything that needs it's own skis. Here's what I have found.
1. You want your edges sharp on whatever you have up there. There are just as many bad days at Jay as good days.
2. Fat is good, but there is too fat. Jay, having tight trees, is a perfect example of a place where you want the ski to work for you. To skinny and you wont float and will stop. But too fat and you can get going way too fast in the tight sections and will be way too concerned with avoiding trees to enjoy the snow.
I have been on skis ranging from 88 underfoot (Volkl AC50) to 132 (Hellbents) at Jay and have found that my favorite so far has been my 186 Prophet 100's.
But it's different for each person. Try some different skis and take what you like and don't like into consideration when buying.
