WELCOME!
I like to recomend SUPERWINCH winches. Excellent product, good prices, stand up company and awesome customer service. For a mount Polaris has one as does kimplex.
Fairleed will depend on what you choose for line. Hawes fair leer will work with either but IMHO is best with syn line. Roller fairleed is best with cable but rollers can be changed for use with synthetic. BUT, NEVER use a used fairleed with syn line!! At least not one that was used with cable, it will quickly destroy your new syn line!
IMHO syn line is a godsend for ATV's. its far lighter and much safer but more costly and will not last as long. Its also not as abrasion resistant and the durable cable. Syn line will never kink, never give you a steel sliver, gloves are optional with use. It spools easy. NO danger of spring back if it breaks. its also stronger than cable and is far lighter in weight.
Cable is more durable and cheaper.
Both work, I choose synthetic.
