The faux governors on Wilesco will draw away power , & Jensens are even worse. you'll probably find that the spring belt gives the best performance Ben. A nitrile belt usually has more grip ...at the cost of being tighter , it's very hard to get a nitrile belt to be loose enough as to not rob to much power & tight enough to work without looking like its gonna fall off all the time.
