My experience is better than that, ive been using belt drive quite a while now with both types ill admit i didnt get on too well with the original carbon drive but the new centre track is excellent. Ive had centre track since july and in that time i have ridden some really muddy rides, SSUK was particularly shitty, the gates sheds mud better than a chain and never gets clogged up. With regards to tension i dont have a tension meter but i do have some common sense. I use an ebb and on the rare occasion ive had to sort the tension i simply bollock the EBB round until i can flex the belt inwardsd about 5mm using a fair bit of pressure. In 6 months i have had to change the bearings on my HT2 bb once, last week. The hub bearings are still running smoothly (american classics) My frame was designed for belt drive and was tested by rohloff to make sure the stays were stiff enough. I use a 39 front and swap between a 22 and 24 on the back giving me close to 32:18 and 32:20, 😀 i love it
