The 391 is an excellent saw, it will out perform a 261, it is a great firewood saw, it gives you more flexibility, no problems pulling a 25 inch bar for the occaisional big tree, sweet spot is a 20" with 3/8ths chain, but we sell most of ours with 25" bars. We will sell three or four a week, we have not had one come back for any reason. With your height you might be better off with a 391 and 25" set up so you don't have to bend over as much. You would be gaining around 3/4 of a hp, and if you really want it to eat wood have them set it up with a 8 pin rim sprocket and a 18" bar, the increased chain speed will make it a wood eating machine. Good luck with your purchase, if you buy a Stihl make sure to buy a six pack of Ultra mix and double your warranty to two years and take advantage of the 9.99 special on ear muffs and safety glasses promo that would normally run about 34.00.
