Here's my measly $.02
First, I am no expert mountain biker. Second, I am not that great at doing jumps. Third, I used to watch a lot of BMX back in the day and a lot of motorcross these days (thanks to my brother who races).
With that said, I don't think the jumps at Tower 93 were designed for high speed, downhillers riding downhill bikes nor trail bikes. Not too many people around here own them and in my humble opinion, you don't need them around here (unless of course you make regular trips to Pisgah).
The jumps out there clearly look like, to me anyhow, that they were designed for low-travel cross country, hardtail or even a rigid. If ridden on one of those bikes, with a BMX mindset, they'll flow just fine. If you're riding your big squish bike and expect to haul arse with a full faced helmet and protective gear like what we just watched on the world cup, I'm afraid you have the wrong trail.
I sat back and watched a bunch of folks riding it from everything to trail bikes to cross country and it appeared to me that folks were jumping the rollers and rolling the jumps. They looked very awkward and it didn't look smooth at all. Then I saw a couple of guys, one on a complete rigid single speed flow through it like butta. It was very cool to see some talented guys ride it with the way it was designed to be ridden.
Again, just my measly $.02
