Transition question...

Hey all!
I normally ride a 7'8" funboard and have a 6'3" x 18 3/8" x 2 3/4" shortboard swallow tail...
My question is, will I be fine changing over? I am around 5'2" and I guess 79kg? Been surfing for a year and a half, started on funboard and that took a while like a week or two before got used to it compared to the longboard I was using when went to a surf school here.
I surf maybe 4 times a week try to go more if work permits, not really unfit, but am overweight for my height. I have used it before and did manage to catch a wave, but was terribly hard to stand up right as kept falling off.
Should I just give it another go? I want to move to Long Beach here in Cape Town. Much better waves, sometimes has barrel and goes up to about 6' or so on nice days.
