I take it they get more in?
Give us an example of one I can look up from English soccer. Please.
Having looked up some standing terraces, from the English, the one whereby, obviously differing height levels, arranged in Bay, with flat top rails (beer cup holder/hole with a bench seat at back , so seating at back and flat rail at front. Made for 2, and 4 person bays. Look Rugby League is somewhat better to watch standing, something about the game, maybe a 'feel the hits' but It's much better standing , watching, but sometime a seat during a lull, ie conversion is good. If done right this could the best quirky aspect that which betters the experience.
