Hello!
My expreience has been that they softed my TU and EX reports for 6 straight months. Some times twice in a month just to see any activity. I can pretty much assure you that they will be checking your accounts and probably both EX and TU.
My advice, after speaking with Barclay Reps is to not apply for anything until the probationary period is over with them.
As alway, YMMV!
