What board should i get for first thruster 13

I am 13 and weigh 92 lbs i am a good longboarder and i have already surfed a fish 5'6 20 inches wide 2 inch thick and i have tryed my fish on 3 ft waves 6 ft faces and i am ok on my fish and usually use it on small stuff. I am a committed surfer and go like 2 or 3 times a week. Im in santa cruz
and ill be surfing indicators or the slot places inside steamer lane which are a little smaller and i am looking at the Al Merrick 5'10 Flyer which is mid 18.25" and thick 2.13". I consider myself a intermidiate surfer. If you suggesting a board for me please suggest a shaper connected to surftech.
