You have to be pretty assertive on TS because most of the time they don't realize that what they're saying in relation to bandit location means nothing to you. If you can get bulls calls then just pull up your kneeboard and you can have a good educated guess, or at least good enough to find him on radar.
I've had good success with the R-3R, however surprisingly I've also had good success with IR missiles and just leaving the radar in search mode to locate and pull up to the enemy. Once you lock the radar they tend to start taking you as more of a threat, so if you can visually ID them when getting close and launch a R-13M1 or R-60M into their tailpipe they will most likely not even know before it's too late. With that being said, my typical loadout is 2x R-3R and 2x R-60M.
