Let's not go overboard with suggestions....
My first suggestion will be to see and evaluate what your film looks like. Is it properly exposed and developed? If it is reasonably well exposed and developed, there is no reason why decent looking prints can't be made with RC with grade 2 or 3 filter. Once you know the film is ok, then see if you have a problem with your enlarging process. Is your darkroom really light tight? Is your safe light really safe? Your developer is not exhausted? Paper not fogged?
Unless all these checks out, going to higher grade filter or paper, or going extraordinary effort to dodge and burn every part of image will be wasted.
Are you able to put your film on a light table or something and take a digital photograph of that? Can you scan or photograph your unsatisfactory print? Let's see what we have here.
