Edinburgh here, can confirm you would definitely struggle to get 5 spots a week. Outside of August there are 2 dedicated clubs (one of which has a long wait before you get your first spot) and a handful of weekly nights.
Glasgow on the other hand has a ton of open mics and is only an hour away so you could probably pick one and gig in both places fairly regularly.
Anyway, good luck with the move and if you do find yourself in Scotland let me know and I'll point you in the right direction!
I'm in Edinburgh too (just got started about midway through this year). You play regularly at The Stand or Monkey Barrel?
Not done Monkey Barrel for ages, have been doing The Stand semi-regular though, Currently still in post fringe recovery but aiming to gig as much as possible for the remainder of the year, am sure our paths will cross at some point!
