First Board. 1.77m tall guy, Board Size?

Hello everyone,
I'm a 1.77m guy and am planning on purchasing my first surfboard. I've been researching a lot and have found sometimes conflicting information. I thought I'd consider Aussie input.
Latest info has me at purchasing a twin fin 7'4¨x 21.50¨x 3.062" board. Is 7.4 a good size for me? or is it too small to begin? Also, no foam (to progress faster apparently)
I will be a weekend surfer. What do you guys think?
