First of all awesome forum. Learning so much here all the time. Thanks

I'm in the market for a secondhand surfboard. Was just wanting to get a professional opinion of the boards I am looking at before I purchase.
My skill level;
Can stand up every time. Not great at getting out back in the huge surf, but the boards i've been riding so far are impossible to duck dive.
I can do a bottom turn (frontside), and have only ever done one backside turn yesterday. I have been hiring boards which have ranged from 6'7 - 7'6ish and are very boyant. I'm I am 5'10-1/2 and 79kg.
I surf in Christchurch New Zealand.
The board will also be semi-shared with my girlfriend who can stand up every time in the mushy waves. Rides them all the way to the beach

What do you guys think of these boards i'm checking out?

$400 NZ is the most i'll spend I think. A fixerupper is off the menu.
