Hi, I'm 6.2, 105kg my first board was Avanti, great stable board and i surfed it (kinda / badly),
Yes the Avanti was a bit heavy and a bugger on windy days to carry, but thats a trade off.
Many of my mates wanted a go and most now have their own board.
(If you can't ride an Avanti, best you give up the idea of being able to Sup altogether)
I now have had my Allwave 9.6 for 18months, great in surf and flat water, well made, (but slight depressions in deck around feet position) very stable, the allwave is the most stable board that i have tried around its length, including Nash Mana and Corban.
