Attn: longboard shapers (need advice)

First of all...
I live in Southern California (Encinitas, CA)
I am 29 years old 5'11 195lbs and in better than average shape (thanks to surfing)
Been surfing a little over a year about 3 to 4(5) times a week for at least 2 hours a day
Primary board is a fat 8' mini mal and my secondary board is a fat 7'3 funboard/big fish
Now I ride my 8' board 90% of time because it is the board I started on and am comfortable with it. I can catch waves (1-5 feet) easily and can move up and down the face decent. I've felt pretty confident in my ability lately so I recently bought the 7'3 board to progress my maneuverability and have done relatively well picking it up. I do plan on taking the smaller board out on most days that are 3 foot or bigger but I still regularly go back to my 8 footer. With all that said, I have been watching some longboarders and have become intrigued enough to possible go and get one.
I want a longboard...
for a big increase in glide speed/power from my 8'
to be able to knee paddle well
to be able to generate and maintain good speed
to be able to walk up and down the deck, from tail to nose
to have solid flotation
The need for turning ability is marginal but I do prefer to use the rails to turn more than using the tail (at least with my current understanding/habits).
So what size, shape, fin setup could accomplish this? What classification of shape better fits my needs, classical or progressive?
Personally, my novice opinion thinks that, in general, a (9 x 23 x 3) is too small for my size/desires...but that a (10 x 23.5 x 3.5) may be too big, but I really don't know which is why I am asking here! Now I have read other posts here and there seems to be a general consensus that "noseriding" boards are slow. I simply want the ability to try to surf the nose but I would much prefer good hydrodynamics for speed instead. As far as fin and rail configurations I am in the dark. Anyways, any advice is highly appreciated, thanks!
BTW... I realize I should talk to a shaper face to face... and I will... but I know there is some great information to be obtained here and am looking forward to learning from you.
