I think tonnage should play into radar detection range to give smaller mechs the ability to get in closer without lighting up on everyone's radar. Here is an example

Thoughts?
Edit: To clear up a little confusion, these are values for initial targeting only. Currently it's set at 800 meters for everything. Transmitting targeting data to all your teammates regardless of how far away they are still works the same as before. This is designed to let you get a little closer before that initial targeting of an untargeted mech can happen.
