Famous question

I started surfing a few months ago and am hooked. I typically surf an 8' mini mal and can catch waves/ride the face...I dont rip by any means. I also have a 5'11 lost puddle jumper which I haven't used a whole lot. When I try to use it in crunchier surf it pearls, it's hard to duckdive bc the volume. I want something for the crunchier surf, where I live (beach break) when the waves pick up, even chest-head high is pretty steep. I was looking at some shortboards, primarily from CI. My question is, I know that my longboard will help me progress, but what about when the surf gets big/steep? I feel like I am limiting my experience not going out on the bigger days. Is there something to be said for just ripping the band aid off and getting the shortboard? I mean I feel like theres going to be a transition even if I continue to ride my mini mal for 10 years.
