Its fairly easy to see who the dock position is with. My advice? You'll have a whole bunch of brown nosing, younger kids pushing you out of their way on that dock.. Only to sit right seat in a twin otter for a few years, IF you get it. Its a bit of a longshot. I also haven't seen anyone go from the -6 into the beaver in ages (It doesn't happen) so you're stuck for PIC to do anything else.
Having knowledge of the coast compares you to exactly every other person on that dock too. Unless it's at the controls of a DHC2, it won't matter to the operators.
Randys a good dude, I've flown/worked alongside him. Operationally you'll have a better understanding having learned from him than many of the other floatplane instructors. His experience is vast..
Get out there and find a 180/185/206 float gig in ON,MB etc. Do a season or two and you'll be all set up to work for Seair, HA, TA, etc here on the coast in a beaver with over a thousand hours PIC if thats seriously what you want to do. Its a rough gig and usually also ends up being seasonal.... Been there done that
Lots of great opportunities east of the rockies. Slate falls, kissising, Kenora, etc etc all usually end up with at least one low timer in their Cessna's for the season. Check with all the ops in and around red lake. Atikokan, Ivanhoe, derry air if they're still around. A few more off the top of my head, sandy lake seaplanes, the chap in st theres has a couple..
