Imo speed runs are much more to do with who you take with you than Eddies. There are quite a few eddies that can push you through quickly. After a certain amount, the 'winning' screens and re-loading take much longer than the runs anyway!

Imo, the real question is who are the best combos for speed runs when taking lvl 1 chars along for some training. Am getting decent speeds with Hallowed and KP + 4 x anyone else.
