..... The 261 blocks better though.
No comparisons I have seen have indicated that - but a lot of variables are involved, so it may well happen now and then.
The disadvantages of the MS261 always are there, but they are of course not as important when blocking as when limbing etc, out in the woods.
Each to their own though - and for using the bars off the 461 on a 50cc or smaller saw, there really aren't any option to the 261.
