Nice muni Marco! But just a suggestion:
Ditch the Rubber Queen and get a Rain King or Der Kaiser! Rubber Queens are notorious in trials for being extremely pinchy and having unpredictable bounce/stability as well as not so great grip!- Compared to your standard sticky Maxxis.
The RK/DK Conti tyres however, are undisputed! I’d love to see a muni with one of those tyres!
