I just got a stihl fs 90 R. I think it came with 0.95. im hell on string like its nothing. Would .105 hold up better. hell what does everybody else uses?
How's that? Blades run me less than $1 a piece.Edging with the line trimmer will waste a lot of string but it is better in cost than changing out blades.
Bingo...........we have a winner!!!Last year when I was running a crew I went through 13 lawns(not small) with 1 spool from one of our FS 90's. My technique is letting the tip cut only and not the entire string. 0.095.
