I've got an Elimimnator set, and I frequently go between double and single pedal setups. (Like TheIronCobr4, I also change setups to improve creativity - played a 3 piece for band practice on Saturday, it was great!)
The great thing is that you don't *always* have to use a double. I waited till I was proficient with a single before putting down the cash for the elims, so I am comfortable with both. There ARE technical advantages to using doubles- flams, more 'even' power with double hits, but I think of it in terms of what's the worst that could happen? The link, slave pedal and beater sit unused in the case? Heck, if you REALLY find you don't want it and go back to singles, find another aspiring metal drummer to relieve them from you!
