The Steppir will give you 180 in a few seconds.  Get the DB36!

I often run with the stack on EU and then jump to the 4-sq if I get a caller that I can't make out from another direction because he's off the side or back.  I was going to take down the 4sq but the ability to point in some other direction instantly is a real help especially in contesting.
