Hi everyone, I've got a Seagull Decathlon that I've flown with a few times (my second plane and first taildragger). Each time I struggle taking it off (fly and land just fine). I can't keep the plane tracking straight. I know taildraggers tend to pull some, but is this one tougher than others? Should I be flying a different tail dragger?

Couple tips I received: take the spring off the tail wheel and replace with straight rod, bigger wheel on the tail. I love the set-up I have with this plane, but I am getting highly frustrated at this point. Thanks in advance.
