mobowhuntr, I would suggest that before you make any knid of changes at all that you shoot you 400's with broadheads and see how they fly. It might get a bit ugly, but at least you'll know for yourself. And with no more expenditures. And whos ays that you HAVE to shoot all that weight. You may find, by turning the bow down a turn, that your arrow just might work. In that case why spend more money. I don't think any north american game, whether it be flesh or rubber, will know the difference between 70 and 67 lbs.

But I am with the other guys in thinking that the 400's just aren't stiff enough for such a setup.
