nothing under 4/10 flex is going to be great for kickers. you're going to have to compromise a little bit somewhere. honestly, you should be able to get some good flex out of your banana if you're 170 lbs and riding a 154. if that's not flexible enough for you, you're only option is to get a noodle board (Artifact Rocker) and avoid really big jumps.
Idk rookie like I tried last season believe me. I wasn't able to clear rails to the best of my ability. It was a medium flex. I didn't like that about it.
Can you suggest me a couple of boards knowing my style that can handle kickers and is flexible. Eventhough you said ill have to compromise a little, but I wanna see some options so I can research them.
