Had a period 3+ years ago of very little hair, but once it started to grow back I tended to let it get a bit longer! We are not talking "hippie" length, but just enough for tlLB to run her fingers through.
I quite liked the No.2 look and that would be the preferred route, if required in future.
As for the "comb-over" I once saw one go up and down like a trap door, when a London tube train came into the station.
