You mentioned bass bugs so I'm guessing a WF bass or "clouoser" taper with more of the fly line front loaded would be a good bet. Check the line profiles below:

The other question would be why you are wading so deep? Perhaps wading not so deep to as to constrict your casting allowing you to casting further would be an option. Another question I would have is whether you are hitting the water in back of you with your backcast.
A video of you casting would help in identifying ways to improve your casting.
