Line lock or leave as is?

Excessive spinning of tires $359.00C
Everything is $359.00C, now, one size fits all.

Ok maybe not all, exactly but it sure seems like it, I better start paying by check for the paper-trail,lol.

But I don't get it, Who determines if it is or is not excessive? I mean first gear or second,even third
Sometimes I just put the line loc-on, shock the tires loose, and sit there just above idle in first gear, with the BFGs barely turning;moaning and howling. Same ticket!
