Keep in mind that these concepts, especially the names, are very rough sketches put together just to gauge general reactions.
I'm sure they're looking for statistical deviations between the reactions of various demographics for each concept. If a ton of younger families lean toward the pony express coaster, that would really appeal to the PTB versus a wooden coaster that is more of a general audience pleaser. I'm feeling more and more like the shot tower is in there just to act as a backup or to provide a third option for statistical purposes or something. It just doesn't seem like a route the PTB would go unless they're actually planning to purchase a new, larger tower.
I really don't know if the pony express coaster would really help them with the younger demographic versus a wooden coaster though, the novelty really seems like it wears off fairly quickly on most of these motocoasters. However, adding a farther-appealing wooden coaster may bring in too much of a thrill seeker demographic than the park wants to deal with right now. I feel like if they do go the wooden coaster route, they may aim it towards a smaller profile instead of something larger. I don't even know if they'll go as big as Prowler at WoF, though I'd be ecstatic if they got anything like that.
Just my thoughts, what do you all think they're really gauging?
