Keep them both.

Tomlin has talent and has done some good things when trusted to play. He may turn out to be a bad signing but it is too soon to say yet.

Pilks has shown in recent games that he is back on his B+ game and able to do a good job. Warnock has implied he is no longer actively trying to move him on.

Unless there is a real problem with squad salary costs (can't see getting much of a fee if any for Pilks but he would be taken by another Championship side - like Ipswich or Bolton) then why weaken our squad and improve a competitor?
