MF, 17cc is plenty for trimming a regularly mown lawn edge - fairly sure at least 5 of the trimmers I have are 17cc or there abouts (Couple old echos, Ryobis and Stihls from early 80s).
But yes, gutless if the going gets remotely rough
Was using my only 4 st line trimmer (90s Ryobi 875r ) the other day - much less vibration than many newer half crank 2 strokes, and went perfectly over the lawn edges.
Only needed enough throttle to lock the clutch and the high torque pulled through really well
Then went at the side verge where some strappy weeds have popped up with the rain - full throttle it revs exactly on spec but is thoroughly gutless since its 4 stroke
