Has anyone here viewed the 2 Internal Power Dynamics DVDs by Mike Patterson? Mike Patterson teachs hsing I, ba gua, and tai ji for competitin and fighting. I was wondering if anyone thinks the power building excercises are beneficial to those who already have experience.

Normally I mightve just bought it and made my own assessment but the DVD is only 35 min and it costs $35. That's a dollar a minute! A little too pricey to be buying on the fly, IMO
