Never heard a bad thing about Ricky's School or his DVD's but as I've never seen the DVD's and don't know the content or how much detail Ricky's goes into about all aspects of shooting form like the basics of good body alignment, correct finger position, back tension, follow through etc
Maybe waiting4fall can send me a free copy ;-) or if somebody has wached both MBB's series and Ricky's DVD's can give an opinion as to which was most informative.
