Later throughout the week it varied from 3-4 feet to 2-3 feet which was still great for learning and made it easier to get out there.
Unfortunately, I don't know what board I was renting precisely but it was a 9 foot foam board. I imagine it was the same as every other foam board out there, just branded differently

All in all, had a great time. I imagine I will try and get back out there next weekend.
At what skill level should someone upgrade from a foam board? And when I do, would a 7'6 Addvance board be a good option to move to? I have the option of purchasing one at a great price ($375) from someone I met. I'd also just like to confirm that it is a good price haha. It doesn't look to be damaged whatsoever... I also imagine I will test run it before I purchase. However, they say the board acts a lot like a long board, as does what little research I can find on the board. Fireware's site says that it can be used by beginner's... but I'd really just like opinions. I've heard length matters by so many people, and perhaps I will pass on the deal.
I did notice that fireware's site has two different options for the board... two different materials. Are they both sufficiently good for a beginner?
I probably won't use it right away, and will continue renting a foam board for some time... but just curious about opinions. I may purchase it if you guys think it's a good next step, even though I won't use it for quite some time.
Edit:
I should note, I know I'm probably not ready for this board at the moment. But I want to know if it's a good "next logical step" after a 9 foot foam board. I can catch waves pretty easily, turn... take advantage of the upper part of the wave for speed... I'm sure there's a lot more to learn but that's where I'm at. I also figured you may need my height/weight. I'm 6'1-6'2 and about 165 pounds.
Appreciate the help!
