Should I get a shorter board?

I was surfing on a 7'10" egg shapped funboard, it was pretty thick board, sometimes I felt like the board was slow, and I the control wasn't good so that I could build speed. This board is broken now, so forget about it.
Recently I surfed on my friends 7'8" that instead of being the traditional egg shapped board, has more of a pulled in nose (a little bit more triangular) and has a squash tail. I did feel I had more control over the board and I was able to get more speed. This board had a weird width, 23" wide.
So, now I am shopping for a new one, and I would like more control. I don't wanna jump to a shortboard yet. I am thinking of getting a 7'8" or a 7'6".
Would it help me with control and speed? Would a 7'6 fun be too small for me since I am 6'1 tall and weigth 175lbs?
Someone I know is selling this board below, looks like this shape could give me more control cause it's kind of hybrid. What do you think? It's a 7'6.
I appreciate your help.
Thanks
