A 6 wt rod would provide the greatest versitility for the fish you are planning to target. It can cast wind-resistent bass bugs for the bass and is not too heavy to be able to have fun with the smaller fish and the small flies some of them will require. You should simply choose the 6 wt rod in the series you like the casting action and feel of to get the best one for you. Since you live near the factory, you should be able to cast several different models in different lengths and then buy the one you like best.
A 5 wt could be used; but it will be decidedly light for the bass bugs.
