I have a 8' Bing Collector on the way to Oregon this week and I'm looking for fin recommendations. The board has 4+1 FCS. I'm 200lbs (add another 5-10 for wetsuit), 5'10 and I'll primarily be surfing in Oregon. I'm somewhere between beginner and intermediate. I'm reading up all the information on fins, but haven't gotten a clear idea of good starting points. I'd like to have options and then try them out (single, 2+1, quad) to figure out what I like for the conditions of the day at my skill level. The board comes with a set of FCS quads which I'll try out. I also have a 8" Larry Allison flex fin. I had read that board length + 1" is a good place to start on a single fin so should I look at a 9"? I was considering another Allison Flex or a 4a. Any others I should consider? What setup should I look at for a 2+1 setup? Would the 8" with small side bites be too much fin? Added picture of the board: Thanks all!
