Is a 6'3 micro egg adapted to me?

[SurfinChicken]

Bonjour!
I am going to change of board, right now i have a 7' foamie from "olaian", it works really great in small conditions (>3 ft) because of its volume (60l) and my weight (55kg).
But it has almost no rocker, so i can't ride bigger waves because then the nose goes under water.
I contacted a shaper, very nice guy, in Oleron (the island in France where i surf) who can shape me a 6'3 egg (or micro egg?) for 550€.
I wanted to ask if this kind of board, around 40l of volume, is adapted to me.
I am 175cm tall and i weight 55kg as i said. I'm a teenager so i might grow up a little bit, but I think i' ll never weight more than 65kg.
I am surfing summer waves (1-5fts) in a beach break. My surfing level is between beginner and intermediate, my takeoff is (almost) clean, I can surf backside and frontside, take speed, sometimes bottom turn in frontside (backside when I am very lucky) and that's all.
I wanted to ask too if I can go for a hybrid fish, like a rnf or puddle fish, and what's the difference between a big hybrid fish (6+) and a small egg (6'6-).
I think that's all, thank you for your answers!
