Advice wanted on season passes for Summit County

I will be relocating to Denver for the winter, and will be hitting the
Summit County areas a lot. I will initially be unemployed, but hope to
get a gig while I am there. Anyway, suffice it to say that I will be
trying to ski every other day.

I figure that every week, I will ski at least 1 of the weekend days per
week, and will try to catch a day or 2 on the side after work. For
this reason, it seems that I must make Keystone as my primary ski area.
I have enjoyed Arapahoe in the past, although it would be nice if they
groomed a bit more. I have never liked Breckenridge, and really do not
understand what the fuss is all about there. So it seems that as a
basis, I should purchase the Ski 3 Pass for $359. If I read it
correctly, that pass allows me unlimited skiing at those areas.

However, I also enjoy Copper. Of course, it is only a day ski area,
and I would need to get out the house early to get a full day of
skiing. It would really be nice if I could somehow get a pass that
included the Ski 3 and Copper together for just a little more than the
price of the Ski 3 Pass, but I am wondering if it makes sense for me.
It looks like a 1/2 day ticket is only $50, so I could do 5 days and it
would still be less than getting a season pass. But then again, I
would plan to do about 32 or so skier days in the season, so even with
a combined price of $640, that would still be about $20 per day.

What do you all think?
