if you want to feel safe, get a net. i dont have one, and its sketch. well it has zero padding, a rusty metal pipe allaround it and super rust springs. best one around.
so if i were you i would get the one with a net so you can huck anything you want, and use it as a slingshot to fire stuff at your neighbors house (if u get the flex poles)
Get the one with springs and you can then cross them and bounce higher, if you dont have springs you can bounce but with more then 1 person on it, there is ZERO bounce.
-Springs (crossable)
-Net (if u wanna huck shit)
-Big (more ppl = more fun)
thats basically it.
oh and when you get better you should be able to drop the nets if you want to make an edit, the net makes u look non-pro. and u cant film through it.
hope this helps.
I got my tramp from my neighbours when they were renovating, its the BEST!

. oh and put your tramp beside a tree so you can jump off it and stuff.
