Older 3 stage board advise

I am thinking about giving a 3-stage board a try and since I am not sure that it will be for me, I think that I will purchase either a new or used prior year model. I currently ride a Hyperlite TFD DNA 142 and a Hyperlite Belmont 144. Both these boards are continuous rockers and I would like to have more pop from my board. Can anyone give me advise on what would be a great 3-stage board what rides okay in chop (we rarely have glass), lands fairly soft and POPS high. It would also be good if it was a board that I could more easily transition to from what I currently ride. I have heard that the Liquid Force Substance and CWB Absolute might be good choices (I weight 180 lbs and am 6'). Any years better than others?
Thanks for your help.
