Old Board shield is ugly as fuck, old heater shield won't save you from good archers (it leaves huge portion of your legs uncovered...)
You really care about how a shield looks?
I thought shields were meant to shield the guy behind them from arrows and melee. (At least 'till I chop it to bits with a Great Long Bardiche.) That being said, archery issues are typically easily fixed by shielders. You're a shielder? Hurrah, keep your head on a swivel and your shield up, 2h/non-hoplite Polearmer? Stand behind your shielder, he's there to tank for you.
Also, you're forgetting about Kite shields, Plain Kite Shield covers most of your legs satisfactory(As does the rest of the Kite Shield family).
