I have both a 2wt and a 3wt; like you I use them primarily for small pan fish and they are great fun. For the 3 I have both WF and DT lines. I bought the DT first, but I must say that since I got the WF I haven't even had the DT spool on the reel. I'm sure they each have their place and their own advantages; I just haven't found any for the DT to outweight the WF. JMHO.
