I can tell you with the Magnus, it will make no difference what so ever. I got a package of them, took one out, screwed it on, and shot it. It shot perfectly. I didn't spin the insert to get the wobble out, nothing. In fact, it didn't wobble anyway..As for the Muzzy 3 blade, personally, and others will probably disagree, it doesn't matter, as long as there is NO WOBBLE AT ALL. But, I like the Stinger so well, I am taking all of my beloved Muzzys off.
