I know I'm just a stranger on the internet, but I'd strongly recommend a clear Remo Powerstroke 3 on the bass batter head if you want something new. Otherwise the stock clear head also sounds great as long as you use the Yamaha Impact Strip. Mine I use the stock head on the bass batter and it works well. http://www.amazon.com/Yamaha-MA-200-15-Feet-Impact-Strips/dp/B0002F6XK4
