Wow use dude this is a breakthrough in twinkling culture as we know it! Thank you so much! Maybe I can find a way to work this into my new FC route I've been working on!! (it's not new, but I mean it helps the new tinks I guess)
There is actually a way to get up top of tun using the start of that jump but it's incredibly unreliable. I've only pulled it off 2 or 3 times out of about 100 attempts back when I searched the world for any and all jumps. I was much better at sticking them back then too so it would be even less reliable now.
