No way, rossi bindings are way more burly then marker bindings. The rossi SAS 120s are very durable, they have metal in them, as opposed to plastic. The rossi bindings are heavier then the marker, but they are more durable. The marker bindings are lighter but not as durable.
Its your decision...
There I found you a pretty sweet deal, for both the marker griffons and rossi bindings on evogear:
Since your 115 lbs and obviously not as heavy as the bigger older kids. I'd go with the marker griffons.
