Would fishing improve if you took out approx 1/2 the branches of the trees first? It may not make much difference if it is a pile you are after, but for just a few trees, maybe thinner is better?

I have been noticing the Christmas trees that I have sunk have such dense branches and crud on them that there is no room left except for the smallest of fish. Darned wives have to pick out the trees that can squeeze on the most ornaments.
