Human Factors; Procedure
Working ARF during the Company's mid inbound. The B777; Air Carrier Y was on final; cleared for the visual approach and talking to Memphis Tower. Air Carrier X was also on final; cleared for the approach and I thought I had switched him to Memphis Tower as well. When my Supervisor asked if I was still talking to the A310; Air Carrier X; and did I have 4 miles; I stated 'He's talking to the Tower; I don't know' then went back and tried to switch him to the Tower again. He answered with contacting the Tower. When I put up the splat T; it was less than the 4 miles needed since the B777 is a B weight category.  I'm not sure there's really any sort of recommendation to solve this. The RECAT wake turbulence standards are all new and something we're still getting used to. If anything; maybe move the letters that indicate the category some where else. The B is easy to read as a RNAV Heavy aircraft.
M03 Controller described a loss of wake turbulence separation when the frequency transfer to MEM Tower was uncertain; the reporter suggesting new RECAT identifiers/information for the Data Blocks.
