I had those vito's reeds and they cracked the same place you said. I ended up putting my stock reeds back in and just broke one recently. I'd recommend to stay away from those dual stage reeds, they seem like they break easy.
I'm thinking the cause of this could be from you running rich or a heavy premix ratio, maybe even a combination of both. Running rich seems to be what broke my stock petals recently. What size jets are you running, and what ratio are you mixing at?
