You definitly don't need the longer chassis to be fast with the 210. From what I've seen locally (astro turf in Canada) the rb6 is no better, definitly not $150+ better. The x6^3 will be a very nice car and depending how you are currently set up don't count that out. The only 'one off' parts you might ever break is the rear arms and shock tower, both of are extremely strong (made and moulded in the USA, you'll notice the plastic quality, I'd say its better then xray even) I'd go x6^3 over rb6. The dex210 (which I currently and will continue to run) is a great car with lots of adjustability which is really nice. Out of the box, the only upgrades I had for a while is the RF pivot block and the steering rack, both which I sell (no more racks though) so I put them on because I could, the rack is all you really need. I now have carbon towers front and rear and alloy shock caps on the way because I can. You can still run RM with your B4, it just may take some time to get a good set up. A couple locals still run RM (with the 22 and rb6) so it can be made fast, set up may seem a little crazy from what you're used to though. t the end of the day, all the new 2wd set ups can be made fast, all comes down to set up
