Which attachments do you have for your Stihl Kombi system & which of them do you use the most? Im looking to ad a few to my collection. Right now I have the KM130 power head with the stright trimmer, pole saw with extension pole & the adjustable hedge trimmer attachments. I use all of these tools alot. Im thinking about adding the blower and stright edger attachments soon. What are your thughts on these attachments?
