With pace everything depends on your opponent - if you are of equal power or stronger, it is possible to use LI, because it will make your chances to hit the basket better, but if the defense of your opponent is stronger that your attack, better to use PTB - in total the rate of successful hits will be nearly the same (but you'll have more throws) due to the earlier final attacks with PTB with minimum chance for success of 20%, despite of often delays in attacks and lower % of final success with LI against strong defense if attack is performed on last seconds of ball possession.
