Eichler whacked his Trad Slam with Muzzy Phantoms.
I've used Mag 125s and other similar replacable blade non-cut on contacts. From my bows in the 50# range on arrows with a toal weight of 500-570 grains they work fine.
I like Snuffers but can never get as consistent flight out of them as I would like.
If I felt a need to use a cut on contact 3 blade fixed, of what's now available I would probably go with the 125 Snuffer SS.
That being said, I still like 2 blade cut on contacts best. The Magnus 125's I prefer fly great & simply go in one side of deer & out the other...
