I just got done with 3 ten hour days on a stihl weedeater. I use the head that I load precut 8 inch pieces. A speedloader would not last a day with me!
Is this the line head you are using for your Stihl?
Yes, I believe it is! I have never used one before this job, to be honest, and I really like it. I use a lot of trigger control around trees, stakes, rocks , etc to prolong the use of my line. All the heads I used before were the speed load type.
