T-Brakes, Linelocks and 2steps

[BR3W CITY]

So I sort of understand the uses for these, but having never run them myself I get quite confused. None of my builds are "competitive" just fun street cars, but I'd like to see if I can do a little better than just foot-braking.

My truck runs a 4l80e, and right now manual brakes (front disc w/wilwoods, rear drum).

So, a linelock would lock my front discs, allowing me to do burnouts but not really having any effect on my launch (since the power would be pushing past the brakes)

A t-brake would mean I can load the drivetrain, effectively "dumping" the power onto the drivetrain and launching.

A 2 step just adds an artificial rev limiter, allowing me to footbrake easier?

Help me out here, do you need to run these in combination or????
I'm actually the most interested in a 2step, but NEED some guidance on this one.
