Eight of my top-10 are steel; Phoenix and El Toro are the only wood coasters. I see a disturbing trend with wood coasters (not Intamins or RMCs) where they seem to be built without any aspirations to be great, or that get extra credit for being made from wood even if their layouts aren't as good as the steel counterparts. I can hardly blame GCI* for this, as it's fine to have a niche of making fun family coasters, but when the top-ranked steel coasters are mostly hyper-style, maybe that's should be a hint to parks that people like heights, speed, and air! It's a shame, because the massive wooden structure looks awesome, and the ones that aspire to be great (e.g. El Toro) are. The size (so cost) isn't even the critical factor, as Phoenix shows.
As for inversions versus airtime, I definitely prefer airtime, and I prefer ejector air to floater. The way I see it is that when I'm sitting down, the natural feeling is 1G. Feeling 0G is less natural and thus a more interesting sensation, but then negative forces must be even more unnatural and even more interesting. The feeling of a long floater hill like on B&Ms is pretty cool, though, and I think there's no reason that manufacturers should feel they have to choose one or the other as their MO. My desire to feel something unnatural explains my dislike of hang time, I think; if I'm upside down, the expectation is that I would fall into the harness and hang like that. Many inversions have positive forces, but what I found really cool were the inversions on Wicked Cyclone (my only RMC so far) where I was upside down, but floating just like I would expect on Diamondback. The zero-G stall was awesome and should become the standard element on dedicated inversion coasters over the zero-G roll.**
*I only know Hershey's GCIs and am not impressed. What are their other coasters like, force-wise? Do Gold Striker and Prowler (for example) have solid airtime comparable to good steel coasters? (I don't mean Skyrush.)
**I went across the park and rode their Batman floorless coaster. That zero-G roll gave no floater air, as I think the rotation negated the airtime. Had it been a stall rather than rolling the whole time, there would not have have been any rotation to counteract the floater air.
