For sunfish you want a fast action or even moderate rod. For bass you want a faster action. A longer rod will give you better casting distance, but you should still get decent distance from the shorter rod. I fish a Loomis Trout series UL that is 6'7" and distance is almost the same as my 7' rods. A tip regarding line, use a small diameter braid to get better casting distance, it really does help.
