I don't know what surfaces you use, but I find the No Rules to be a pretty decent house shot ball for many. Would recommend the Trick more so for tough sport patterns.
But if you like the Trick for house, Trick, No Rules Pearl, and Desert Ops should keep you covered in my opinion. As a potential gap filler between the IQ Tour and No Rules pearl, I would say either a ball like a Truth Pearl, Black Ops, or Torrent. As others have mentioned, probably can wait on another ball unless something is losing it's power or feel there's that big of a gap. Any idea which direction you're headed towards?
