So did you do anything yet, it's been days already lol.
I like picco chain a lot and have it on a mm 261. Not because it cuts faster, but less mess on a clients yard, the chips are very easy do hit with a backpack blower and watch them disappear. I also run it on my ported 241 and like it a lot.
Seems most guys dont want to have a bunch of different files and chain sizes around. For me I find it makes it much easier to know what I'm looking for. When I see a 325 chain I can pick it up and tell its for a 16 or 18" bar and tjose go with the small mount bars for the little huskys, the 3/8 goes on the 20+ bars and large mounts, the picco is for all the smaller saws with the exception of the 261, but they are all easy to separate by length. If I didn't run the pole saw/200/201/193 I'd probably consider changing the 4300 and the 241 over to 325 but its not a big deal either way for me, if I have chains of a certain size and saws set up for them, I run them.
I don't think most of the cutting gains are as big as some want to make them out to be if your chains are set up well for the saw. Picco and 325nk or standard I find to be smoother and more enjoyable to run when dealing with small limbs on a smaller saw(50cc or less).
Curious what you decide and the result you have. As was said in the first response, give it a try and see if you like it.
