Your favorite hill workout

I just bought a trainer (should be here by the end of the week). It's a Cycleops fluid 2, and can't wait to use it.<br><br>
I have one Spinervals DVD that a friend gave me - 17.0 base building. I think that'll be useful, and I'm happy that it's a 75 minute workout. And, I'm probably going to buy the Lake Placid training DVD that is 3 hours.<br><br>
But what I need now, since I'm training for a very hilly half IM, are recommendations for the best hill training DVDs. What are your favorites?<br><br>
Thanks!!
