I'd choose a slightly different path. I'll be conected to BB practically on any chance I got from Monday to Wednesday, basically, because there you have les managers conected, therefore, less competition.
If your rivals try to counter your buying, they'll have to overpay more than you.
Right now, I see more inside than outside players. The closer to the deadline we are, the more you'll have to pay. If you want inside players, now is the time, the TL is full of great post players.
Something else I noticed is that you also have more chances of nagging better prices when the player is a free agent, and his owner appears as retired...
