Nice, do you know all the commands for UrT? I find it really important on large maps to listen to the audio - you can hear if people are coming near you. That said, when you crawl or walk slowly (for me it's shift+walk) people can't hear my footsteps. I assume you know that healing yourself by pressing "q" is important too.
I use (my eagle setup):
DE (good for close corners - can kill really quickly)
Vest Helmet (Sometimes this switches with tac goggles)
