no.. there is no difference
but i understand about working 10 hours... plus Black ops 2 is awesome!! BTW- you PS3 or xbox?? anyway....
yea.. thats like me and my leveling kit. ive had it for about 4 months now and i just cant convince myself to go put it on. but that is because it is a several hour and a 12 pack job. just get up and do it
youll be much happier when you do. that reminds me, i need to do my calipers too
