Not necessarily. It depends on whether you want a step up from the Nexxxus, or step down. If a step down, then the Meanstreak does it nicely and I agree with Chris.
If a step up, then the cover is easily tweaked to handle a bit more volume. My Nexxxus was longer and more angular for me than the Brawler has been.
If you truly have trouble getting solids to hit for you then the Brawler is a good go-between. The blue is solid, while the copper and gold are the pearl. Either way, we are glad to help you if we can with layouts, etc. after you make your choice.
What lane surface are you on, and do you have any idea regarding volume? These are things to consider, too. Keep us posted.
