:You can run a stihl mini spline drum and use 3/8lp and .325 stihl specific rims. Then you can use an Oregon or brand x small spline drum and use 1/4 or .325. There must be at least one spur drive drum in the parts sheet.The 241 has a pico chain anyway.
I’m leaning towards the 635xp, hopefully it has decent bars available for it. It’s lighter than the Dolkita 431/4300, which is what I’m comparing everything to.
I’m also interested in buying from a repair shop rather than a hardware store—Echos around here.
