I read some of the posts here, but not all 6 pages. Here is the problem I have with FI right now. You had a crew setup in S1. Now they are all in their 60's, in mature leagues, and beginning to retire, but there have not been any instructors, whether FI or any other designation, that have even remotely decent ratings to fill the spots.
There should be a healthy mix of both age and skill. Instead we have a large group of old guys who know how and then a couple coaches that people have tried to cultivate (out of necessity). THis is not that realistic. There should be coaches of all ages and ability (spread out relatively evenly). So maybe 8 guys in their 60's, 12 guys in their 50's and 12 guys in their 40's. And their skills might correspond to their experience. Instead we have 30 guys retiring in a 4 year period.
