Penetration will not be a problem.
A bit more weight to your arrows will make your shot "feel" better.
Your Carbonwoods, can handle a little more weight where they are, BUT much more and they will have to be trimmed a bit shorter. I`m guessing.
If they are flying good, and the bow is not too loud, don`t worry. Just pick a spot when the time comes.
P.M , me your address, and I`ll send you a few weight tubes to try. It will bump up your arrow weight. It might make your shot feel better.
(they just slide inside the shaft)
Penetration won`t be a problem, but I bet your bow will have a better feel with a heavier arrow.
