i personally think the field should be changed about a fair bit. keep the bunkers behind your back line the same but things need moving about. there are so many different types of lay out that you are ruling out by keeping it the same with tweeks. temple complexes are aswome fun to play in. split snake where each team has a section and one in the middle. total straight line of cans great for attacking play. tall to short, short to tall, mini castles complex. id rather see a different field on a sunday than a similar field on a sketchup three days before.
