I do also remember there being a thread on here about adjusting the top pad of the Force3.
Basically, out of the box the pad sits a little to low on the top bar. So you would just undo the top pad velcro and pull it tighter over that bar. It will lift the padding just a bit. Thus increasing the view window just enough that it won't push down on the bill. Plus... you get the added extra padding over that top bar.
