Looking at it from a third party view it seems to me that you have had the most fun playing with your Baja 5b, and you love the 1/5th scale R/C's best, right? I would keep that one. Plus with the GAS engine setup and recovery is also the easiest one to get ready in a hurry and play with when the girly allows it. All you have to keep on standby is the batteries for the radio and reciever and your good to go.
