So, i always wanted to try a GT216 with a drilled out mousse. Its an expensive combo but just wanted to try it so bad. I never used a mousse before and i watched videos, but, it was still a Bitc*! My previous rear tire was a S-12. Most riding i do is rocks and roots in the woods where the soil washed away or it thick black soil full of rocks and roots. I also spend a lot of time in the water. I put this combo to the test the other day and you cant believe how it conforms to the ground and hooks up. A couple of hills that are not super steep but full of rocks jutting out and roots fully exposed without any soil around them at all. you cant hit them with speed really because there are so many obstacles. Normally, you get hung up and lose momentum and then cant get moving again so then you need to turn around and try again. Well, now i can stop dead on these rocks that are wet and then finesse the throttle and clutch and from a stop,and continue, just by weighting my seat and not paddling. The drilled out mousse forms to everything like a track on a skid steer. This tire however i feel like if you break it loose hard on some sharp shale you will cut all the knobs off. I aggressively rode this tire for about 4 hours, but riding like i didnt want to spin and it showed little wear. Just ever so slight corner blemishes. Just wanted to share my experience. Anyone else ever use one?
