nah, Hooper. never had that problem...of course, i've always sat somewhere near the middle, and seat 2-1 once(so close yet so far), but on my very first ride, which was 5-1(you saw us get car 5, too, remember?) both Dark Time Now and i flirted with red-outs. the G's in car 5 coming out of the first drop are INCREDIBLE!! but i've ridden car 5 once mare in June and did not have that problem at all...so i guess i really can't answer your question too well:)!! happened once, kind of, never again in five or any other seat...

ride early, ride often!!!
