Have just bought a 11' pearson arrow and it only has a 7" single fin.
I dont know if this fin is really big enough for just a single fin, and before I go buying some other fins some input about how diiferent set ups would work and what size fins as well. It can acommadate single,tri and quad.
Thoughts would be much appreciated.
Be aware that not all fin boxes are equal in my experience. American and Australian boxes don't always match
