Who uses the SRM-261T? How do you like it? I'm looking for a trimmer with some torque, but still want good head speed to cut grass cleanly. How does the 261T do in tall grass and normal grass cutting. How long can you get the sting out before it bogs down. I'll be going from the 230 model which I use most of the time currently. I use the edgit disk and want something that I can really mow with in small areas.
