That's a lot of rides dude lol. Look at Voyage for example. After the main airtime hills, you're not far off the ground. Or Riddler's Revenge. After the inclined loop, it's all pretty close to the ground. In fact, a lot of B&M's even dig into the ground with trenches for this very reason. I think it's better to keep the intensity up rather than have taller, more drawn out elements. Also, IBox track does have more friction that wooden coasters, it's best to compare it with other steel coasters.
You're a pretty seasoned enthusiast, I was surprised to hear this from you haha
