Personally I much prefer weed + stimulants to alcohol + stimulants. In fact I find the latter combo pretty pointless as the effects work in opposite directions, kinda, so I end up feeling less drunk & less wired than I would've if I'd stuck to one of them. That said I don't really enjoy alcohol anyway.
As for cannabis, it is a very idiosyncratic drug so you'll really have to find out for yourself if it works with stims. I think it's lush, as long as the doses are sane. If you're prone to anxiety from weed (or stimulants for that matter) you might want to be careful combining them - I don't generally get anxious from either alone but combining them in large amounts can make me jumpy as hell sometimes. It normally makes me spaced out as hell though, instead of the normal stimulant focus (I don't see this as a drawback - feels f*ing nice in fact)
btw the above bit about anxiety doesn't apply so much to mdma - in fact mdma + cannabis is about as good it gets. You
might have problems if you're unusually anxiety-prone when you're stoned but it's much less likely to go wrong ime. Bit about being completely spaced-out still holds true for me,
but I like this.
As for the drugs on your list, it's your opinion that matters really but i'd go for mdma/ecstasy first, and adderall second. I hate coke, and ephedra or caffeine would be a complete waste of time.
Hope that helps
