So far I've done three 10-min sessions at SVCO (each time with a different coach). At 17, jumps I realize that I'm not working on anything advanced enough to need a specific coach. I have noticed a slight discrepancy in the quality of the coaching, though. All the coaches I've worked with are obviously very skilled fliers, but they definitely don't seem to be equally skilled at the art of coaching. Last time, while in the tunnel, I had a tough time figuring out what the coach was trying to tell me. That's why I was curious if you recommended a specific coach.
I'll probably just keep trying new coaches until I find the best fit for me.
