There's a former ISU World level Ukranian pair skater who coaches at my rink. He was most active in about the year 2000, but now I think only coaches. He's nice, as in, he didn't like totally blow me off like some others when I was a beginner, but he's very cold and distant, and I've never seen him smile or laugh ever. So, I don't believe he'd be asking me how my day is or anything like that, he'd definitely not be a "rent-a-friend" kinda coach. He seems to get results, though, just nobody else uses him, at least none of the adult skaters. He is most expensive ($80 an hour, but the other coaches are at least 60, and he's got the highest credentials,) but I figure he'll give me the most bang for the buck, but I'll have to see what my experience is when the time comes.
As far as watching him goes, besides his pretty elite level people he coaches (that are mostly from Eastern Europe) more or less fulltime, I did see him coach like a 5-6 year old kid on hockey skates, and it was complete magic what he did with him in an hour. The kid had good posture and could do forward crossovers no problem, starting from being barely able to skate. As far as the Eastern European skaters he mainly coaches, I don't want to bring up too much, but it's quite grueling, 4-5 hours ice time, he's fairly nice, but his female partner is significantly less nice.
