Surfing Waves

hello im new here!
im not too good with boards and i think i need a great overall board with nice paddle
i surf ok, but my new board is too thin and i dont feel comfortable paddling on it.. i think this keeping me from getting better
im 5`7 157 lbs!
what dimensions would be good for me? post models too if you want to
Im posting a picture just in case you wanna see how i surf, i chose a great picture
thaaaaaaanks

Hey, crop that shot really tightly and it'll look like you're doing a lay-back snap and throwing loads of spray

Can't see what the board is from the shot - give us the dimensions of your current board.
I've recently been converted to pod-type boards with a load of volume up front beneath the chest so something like that might be good for you.

hey mann haha i cropped ! haha
i have a 5`10 18 1/4 x 2 5/16
the dimensions are quite nice but the volume of the board inst quite distributed well for what i wanted, what should i ask for ? ive been taking a look on rusty dwarts recently on the net, would it be good ?
