Im getting around -1.6 to -1.7 which for a brief moment is completely OK. Its even within the ASTM standards because its so brief.
Plus remember, it has those Intamin OTSR's which, if youve ridden Storm Runner, they can handle some INTENSE airtime. I dont think El Toro (minus that twisting drop) has as crazy air as SR does down to the actual numbers, however, it does hold them much, much longer than SR.
I think its totally within reason and as I suspected, that drop in back seat will have some punishing airtime.
