I don’t have anything to compare it to as far as performance yet.
I have run it for about 1/5 hours so far on my little home built course I created on my property from field stones I piled up. It has performed great for me on it so far.
The only issue I have had is with the Proline memory foams. During extreme side hilling, I notice the tires on the downhill side will fold under and cause the rig to tumble if I don’t watch it. In one case, I actually popped the tire out of the bead.
I am ready for my newb run at the next urban comp. Hopefully they will have one this month if the weather permits.
Rob, you can take a regular foam and cut some sections so that you have the same shape, only the foam is just a narrow strip. You can run that against the memory foam, and it will help to stiffen the sidewalls, if you don't want to order some new hybrid foams.
