New Board Advice

Hi All,
I have been surfing for many years and am comfortable catching waves and all of the basics. I do not go surfing very often so am still a beginner/intermediate. Currently, I have an 8' mini mal epoxy board, but it is very difficult for me to surf on. I have used my friends boards and they have been much easier. My board is really hard for me to catch waves in and one instructor told me that it was not for my level. I have always had the idea that any longboard is good to progress and easy to catch waves on.
Because this board is not working for me, I am looking at buying a new board. I am 5'4 and 145 lbs and athletic (a waterpolo player). I am looking at the 6'6 7s super fish II as my friend said that he learned on that board and I should get it. I was also going to go to a boardshop and ask around for what they think but i have heard a lot of varying opinions on what board I should get. Does anyone have experience with the 7s super fish and does anyone know if it will be easier for me to catch more waves on than my 8' board?
If anyone has other recommendations it would be greatly appreciated as well. I am looking for a board that is fun and most of all easy to catch waves on and progress my surfing as well.
Thanks!
Erin
