If you have a 4 speed you don't realy need a line lock at the tack. I found that if I go in to the bleach box and stop. Then I just rev her up and dump the clutch she stays right there. When it is time to come out I just ease out of the gas.
On the street it would be nice to have a line lock so I could do the cool guy burn out. She just wont stay put.
