Sorry, but I just gotta say it. If you can't adjust your bridge or truss rod.. both of which you need check with every string change...find another hobby. Either that or just pay somebody to change your strings for you.
Basically what you're saying is.."I want to drive a car, but I can't possibly put gas in it. I just want to get in and drive."
BUT, to actually answer your question..put MTD strings on it! http://www.bassstringsonline.com/MTD-Strings_c_158.html
