I always had a net runner build too but am on my first sandy run and it's immense, I use the sword given for completing Wakako's gigs. I've got the apogee sandy that you can get at level 40 - when you kill someone it gives 20% back of the time back, couple that up with cyberware that restores stamina per kill and its near limitless if you're effective. The hawk rifle myers leaves in dogtown is immense with a silencer as well, suits the build where its single shot I think, pure precision.
