I have never used a straight shaft edger before, but I was wondering what the main difference between the two is. Would a straight shaft edger be better for a taller person? Are they pretty similar to use? Does a straight shaft edger give you the same angle of cut as a curved one? Sorry for all the questions, but my fc75 is on its way out and I was looking at the fc100 or fc110 and was looking for some feedback. Thanks in advance.
