Seriously are you wishing to buy a pre-built model or build your own?
With the current Rocket being in limbo your choice is pretty much limited to an Exocet if you want to build from scratch.
“Life is not a journey to the grave with the intention of arriving safely in a pretty and well-preserved body. But rather, to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming .... WOW what a ride.”
one advantage other than cost and ease of build of Exocet over Rocket is balance. With a driver in/on an Exocet there is perfect 50-50 front to rear weight distribution. Unless you are a salad dodger! Or only eat lettuce.
