Want to do a buggy conversion but wich one???

I look for a buggy or truggy conversion, but i don't know wich one.
I've an Hyper 7 pro on my list and a Mugen MBX5T truggy.
The Jammin X1 CRT RTR too.

The Mugen is realy temptating, but i would like to try a buggy. It's light and should be very fast with my Neu 1515 1Y and a 6s setup

I want to have your comments!

Thank's

David
