i dunno man.. times are times.. BUT i really don't think there is that much differance between the two.. but even with your demo of times the ex COULD run a 16.7 and the ls COULD run a 16.0 and that would be a HUGE differance.. but it could go the other way creating 3 tenths differance which is EXTREMELY close.. not even enough to matter.. i think they are more like that at the extreme end.. like almost the same to maybe 4 tenths off
