Organic whey protein

Hi everyone,

I've been using cheapo whey protein for a few years now, but have recently been reading up about the numerous heavy metals and pesticides that are apparently found in these. Therefore I've been considering switching to one of the organic brands such as tera's whey or warrior whey. Has anyone here tried any of these, and did you get decent results (in terms of muscle development) when using?

Thanks,
J
