tail shape

Hello.. I'm looking at getting a 7.6 second hand board that will probably have 21-22 width. I've been learning on a 8.0 soft top. There's a couple of things I'm wondering about as I look at second hand boards around. The main thing at the moment is the tail shape. My board now has a squash tail. Some of the boards I'm looking at have all the right dimensions but have a swallow tail and look more like a big short board rather than a small long board. I want this board to be right because it's something I'd like to hang onto even if at some point I want to get something else. Because I'm at a beginner level and trying to get some basic skill happening I'm not going out in bigger surf ( 5-6ft + ) but sticking with the 3-5 fters learning to paddle out, catch waves front and back side. I'm guessing I'll be doing this for sometime and then try to add some turns in.
The nose shape is another thing...
I'm not sure if I've made any sense but what do you guys think about nose and tail shape for someone like me?
