There is. It just depends - as always - what your goals are. I thought: Why wait years until getting a double pedal? To then have the typical problems like "getting your left foot into shape as it was always used to sit on the hihat pedal"? I see some sense getting into double pedals right away (if you need it genre wise - but even if you don't, why not develop both feet equally?).I view double pedals as having lots and lots of toms. It's a monster kit type thing. Yeah, looks cool, but if you're just getting started, there's really no need for it. That is, if you're just getting started.
Similar to crossed/open handed playing. The sooner you start with open handed (doesn't mean giving up crossed playing) the better.
So what's wrong for beginners to check out different ways of playing, sound sources (e.g. cowbells)? Some might take a liking in it, some might learn a lesson whether to stick to it or give it up. But as has been said - everybody HAS to do this lesson for him/herself. Reading advice in favour of/against something is one thing, actually checking it out is another thing. Which makes the whole thread obsolete in some sense.
