well, ive been using my 2cycle troy built trimmer for almost 5 years now with very little problems. i always clean the carb at the end of the season, and run a 50:1 mix with 87 octane. It always starts on the 3rd or 4th pull, but now im starting to feel a little sore in my back and neck because im not standing straight up while trimming due to the shorter shaft and 14lbs of weight that it weighs. I went down to the dealer thismorning and lifted a fs 90r off the shelf and was very impressed with the weight (11lbs i think) and balance of it. The shaft is almost 11" longer than the troy built allowing me to stand straight up. Its a very nice unit! dealer wants $399 for it. So i asked him about any end of season pricing and he said they sell for $379 in the spring but would let it go for that price now. Im very tempted to go back and get it but whats the point right now with winter approaching. I hate to lay the TB to rest, but i think for the $400 it might just help with some of the pain i've been experiencing from the TB. Does anybody recommend this trimmer by stihl or a different model?
