blairgowrie native here, so if you need any local advice fire away.
Nevis/Glencoe are both about 2-3 hours (traffic permitting) from here, so i'd probaby save them for when you're based out west.
the glenshee q's will probably be pretty bad, it's only a 1/2 hour drive so you'll gain the time back vs driving to coe/nevis, just be up there super early and you'll get 2 quiet hours first thing while everyone else is standing in line, take a long lunch then stay late for more quietness
you can also get to aviemore via glenshee and/or the lecht, so you can avoid the a9 and grab a day on the way too.
all 5 would be pretty easily doable given your bases.
no idea on lessons etc, but these guys [www.freshtracksglenshee.co.uk
] have a good rep locally.
