For what your looking for, the Hogue really is your best bet. The stock flexing stuff is largely over blown. A lot of guys use Hogues on their Appleseed training rifles (which is all slung up style shooting) and don't seem to have any problems qualifying.
The Hogue's I've had (2) had no noticeable flex. If you get a Hogue and the barrel is not completely free floated, it's not hard to remove some material to make sure it's FF. You can also add some bedding material in between the ribs in the barrel channel to make the forearm more solid if you want.
All that said, if you still decide against the Hogue then I think you would be better off going with a good basic laminated wood stock. If you can find one, the factory laminated stock that comes with the 10/22T is pretty nice for the money. The factory "Deluxe" walnut stock is pretty nice too, especially if you are sticking with the factory barrel. The Revolution TrailBlazer stock is a good basic wood stock with a rollover cheek piece.
