bic 7"3' Minimal OR Bic 7' Egg whats the difference?

Hi And thank you for reading my question and also for any advice you give.
Ive been surfing on and off for 2 years now, and currently have a Bic 7'9 mini mal, I weigh 158lbs (Im losing weight all the time I believe I will end up at around 149lbs) and am 5'6" and whilst this is a great board for me to catch waves on (really easy and lots of fun and a super tough board), it has draw backs too:
1. I struggle to duck dive (its very bouyant).
2. Turns are slower than I would like.
3. Its too wide for me to reach around (so carrying it to the Sea is a pain in the butt).
So I figured my logical next step would be to move down to a 7'3" Bic Minimal, I rented one so I know they turn better and feel faster but then when I went online to purchase I saw they have now released an 7' Egg what is the difference the stats on the site make the 2 board identical in terms of what they do but surely that cant be the case or why would they have 2 boards?

Bic 7'9 board link (my current board) >> http://www.bicsportsurfboards.com/produ ... 2,480.html
I have no intention of getting rid of my exisiting board I do love it, I just want to try somthing faster more manouverable and easier to carry and ideally something I can duck dive with!
So if anyone can explain the difference between the 7'3" minimal and the 7" Egg (other than the shape and length) that would be very helpful.
I mostly surf Beach breaks along the west coast of cornwall, mainly perranporth, but also watergate, & Fisteral.
