I know the aluminum moon nocks are no doubt stronger. I'm thinking of switching to these , however I would like to shoot the 100 gr Grim Reapers that I already have. Will these fly good or would I need to bump it up to 125 gr point? It's shooting good now with the plastic nocks and 100gr pts so I'm kind of hesitant to change. I was told that the plastic nocks will work fine if seated properly against the string and won't fail, but I'm hearing a couple guys saying they broke their plastic nocks and it cut the string. Don't want that to happen. Whats your opinion ?
