Since I am trying to work on a steady higher cadence with Spinervals, I've noticed an improvement in my speed too. Fortunately, almost all of them help with this.
I did 3.0, Suffer-a-rama last night. I find this one a bit irritating. I think it's because it has some longer soft-pedals with that really irritating soft pedal music he uses.
Wouldn't Uphill Grind help on the climbing?
