Need your expert advice. I was looking for a couple of weed wackers for a B25 I am building. It is the smaller Ziroli.

In at Can. Tire they have Weed Eater brand that I believe are poulan 24cc.

In at Wally World they have a 28cc Ryobi weed trimmer. They are 30.00/can. cheaper.

My question .......... which one do guy's think is a better motor? Why?

Thanks in advance, Peter.
