The best solution really varies from person to person - how hard/soft you hair and skin is and such. There's also a somewhat different technique to it, but I'm if you've tried a DE razor you've looked that up.

In my case, I guess I'm pretty lucky - the morning shower is enough to soften the hairs and stubble, and if I shave immediately after leaving the shower it only takes only a few minutes.

But that only goes to show how ridiculously expensive and wasteful a 5-blade cassette would be in my situation.
