Picked up a college pass for Wachusett last week, but I'm going to upgrade to the silver pass for $100's more this week. The only difference is, is thats it's pretty much a gold pass during the pre season and late season.
I'm also getting the three mountain pass to Loon, SundayRiver and SugarLoaf as soon as the college pass goes on sale, which I think is in November. I'll mostly be using it for Loon, probably will only make it out to SR and SL once or twice this season.
I usually get the bronze pass at Wachusett, though last season I sprung for the silver, but the season was so short it was barely worth the upgrade. I may just go for the bronze again.
For weekend trips, I like to keep my options open so I don't go to any specific mountain enough to justify another pass.
