In defense of Petrick, his skiing on the three days of taping the various demos was somewhat subpar. He had just taken a desk job and had not been on the snow in a few weeks. In an effort to portray all three skiers with most all of the demos, we really had to work to find enough of Tim's demos. However his skiing and knowledge was spot on otherwise.
What was/is important, is that these three skiers had very different body types and thus each demo had a slightly different feel to it. Heck, with Jerry's monster quads, his demos had another dimension altogether. Of course, that was and is part of the reason for the name 'Centerline". While I was a co-writer, Jerry, Ellen, Tim and others contributed to the descriptions. I provided the narration for each of the demo descriptions. I took the input from them and developed a proper narrative. This was Jerry's project hands down. I helped conceive of and facilitate the project through Mammoth Mountain, where I worked at the time in the Marketing and video department. I was able to work out a deal to produce it at no cost to the PSIA. When they had an order for more tapes, we would 'sell' copies in bulk after they had the order. This way the PSIA was able to provide this to the membership with virtually zero out of pocket production expenses. I donated my time. Mammoth gained tremendous marketing exposure, which still pays off today in my opinion. I see this production as my most important contribution to the PSIA.
Later that year, we (Mammoth Mountain Video Department), produced the World Mountain Bike Championships on ESPN, with the first Kamikaze Downhill and much more, including slalom racing on mountain bikes. Not PSIA related per se, but it was quite a year for me.
I try to keep up with current PSIA criteria, but it so often seems like rehashing topics that don't need to be rehashed. I recall a few years back when they decided to change the name of instructor 'clinics' to instructor 'pods'. That's when I tend to tune out.
I ran into Jerry a few years back at a Sun Valley PSIA convention. He had recently watched it and felt it still holds up after all these years. The concept was so that an instructor from any division could discuss the criteria for each demo based on the 'centerline' demonstration without having to be present. The video provided the reference. The concept is still valid. Of course, we are talking about certification standards. The rubber meets the road with actual ski instruction.
