So I’ve about decided that I want to buy an Echo CS-490. Purpose is for limbing, use around my home when limbs fall off my pecan tree (weight), etc. I’m not doing huge tree cutting or anything like that but my question is would y’all recommend getting the 20” bar or the 18”? I feel like the 18” would be more than sufficient for what I need but am curious if I’d be better off having more than I need in bar length? Thanks.
