My thoughts against X-Flight,
1) get rid of the 8th row, the train barely leaves the the inversion before getting to the bottom of the drop
2) Why have you not built the thematic feature the inline twist was meant to go through.
other than them two things it could be a dandy ride to go on!
By the way, X-Flight has a different drop to swarm, swarm as a more horizontal inline twist before dropping but X-Flight starts dropping halfway through the inline.
