Line Lock vs Trans Brake

[3ponyshow]

I have a basic understanding of how they both work, but for a 4R70W, which works better for the strip? Which is more cost effective?

I wouldn't use a line-lock at the strip except for the burn-out. I'd expect a high-power engine coupled with sticky meats to simply slide the front tires and cause a red-light.

If you've got a serious motor and converter, get the trans brake.

Trinity_gt gave good advice. Ideally, you'd want both; line lock for the burnout, and trans brake for the actual launch. If you can only afford one, get the trans brake.
