Tumble
I use this:
Basic tumble check past one opponent is 10 + 5 per 5ft movement on the threatened area. Tumbling through same square as opponents is in adds 10 to DC of the check. If you tumble past multiple opponents, add 5 per addional opponent. Opponents that occupy more than 5x5 area add 10 to tumble DC through the same area as they are only once, every square after that adds only 5.
So 5ft tumble past opponent DC 15, 20ft tumble DC 30, past 4 guards DC 45. That should be hard enough and makes Mobility feat more worthwhile.
