Another option is to dual-home all of your access-layer switches to the dist switches. You can create 2 trunks on each access switch, one to each dist switch, and configure each of them via STP so that (for instance) your even numbered vlans go to dist switch #1 and fail over to switch #2, and your odd vlans go to dist switch #2 and fail to dist switch #1. That way, you're load balancing all access switches between both dist switches AND providing redundancy. The only "price" you pay is having 2 connections from each access switch instead of one.

The diagram shows this technique being used between the core and dist, but you can apply the same concept with access and dist. HTH, Mike W.
