i have 2 co`s
now other pally has one
had 3 meeting with my one`s played alot
1 of these co`s came of ebay ,so i done what i knew best .
never had a issue with the roar`s or monster`s . i used roars indoors on carpet/rubber`s never over heated
but i think this co will have a small gearing window like the roar has
but it`s got a nice blue can to go with my preeeety blue evo 4
i only need a couple of meets to find if it works or not
And what i found is every thing works it`s just applying it at the right track & right gearing
