Replying to How hard are frontside 450s

So my current hill just built their big park with a massive upward tube that I’ve been dying to hit + 450 a bit ago and I’ve gone hard in the paint learning how to hit + 270 off most tubes/flat rails. What I wanna know is how hard is it to step up to a frontside 450 off of something that’ll give me enough hang time to possibly get silly. I can’t really 360 that well hahaha but I feel like I’ve got a solid handle on my frontside 270s. What do y’all think?
