But I use IB as a feed for Medved Quotetracker as a backup for my main setup of TS2Ki with IQFeed for 2Ki (using Dynastore for IQFeed.) That combo works well. I imagine that TS2Ki with IB would work equally well, except I believe that IB's feed has a [small] symbol limit - sort of a bummer if you use RadarScreen to scan for conditions over many symbols...
