Surfing Waves

hi i surf about 2-3 times a week been riding a 7'0 ive been trying to go smaller there is a 6'0 doc surfboard for sale around my area and i was wondering your opinions on whether i should get the board or not. Thanks. im also fast at learning to stand on new boards.

If you are riding comfortably , then your size and weight should do OK on the Doc board.
How's your wave catching? If you are not catching all the waves you set out to paddle for, you will find going down in size may well mean less waves until you adjust, if the Doc is a little thicker or is surftech or epoxy based then you may still have the paddle power. See if you can try the board>
