For me it's basically Brian Orser videos versus Nick Perna videos.
MySkateCoach.com has Brian Orser and I really like his videos of him teaching exercises to a class.
ICoachSkating.com has Nick Perna. I've seen some videos of him teaching on you Tube, and he's really good.
MySkateCoach has more versions than you can shake a skate at. Free, $7 a month, $25 videos a month with different levels of discounts for video purchasing and different services. http://myskatecoach.com/product/subscription-plans/
I like how you can purchase videos and sample them
ICoachSkating.com is subscription and requires Paypal. Cost is $29.97 a month. You can get sample videos by signing up for their email list.
Videos: MySkateCoach about 4 minutes long, with annoying 1 minute intro. ICoachSkating, about 6 minutes long without an intro.
Anyone have any comments? Discussion about one or the other?
