I also have a blister on my forearm.  I was using a Limbsaverstrap while using the trimmer.  I also love/hate this trimmer.  The power and reliability are awesome.  I also feel it was a good value.  That said, I personally would consider paying a few dollars for a decent looking pop-in cover that would keep my forearm off the hot plastic, but still allow me to use my forearm for positioning/leverage when needed.  I am very consious of my body positioning, but trimming a ditchline puts your forearm on the casing of a trimmer... it just does.... so, back to the cover - 1 inch of airspace and a nice 2" radius rolled edge at the front... 4 pins for a standoff, capable of 40 lbs pressure... ie 1 handed operation if necessary (don't tell OSHA). 

If Husqvarna isn't planning to do anything with this, let me know, Icould have 100 made as cheap as 1, and put them on ebay :).
