    I think your going to be hard pressed to get 18#s out of an SC-Trim on that combo. I would recommend an 8"/2.95" combo. I think that might yield you 14-16#s with minimal belt slip, but its going to be maxed out. Maybe 10 rib would hold more, but your just going to be spinning the hell out of that blower.
