I have the dual drivers. IMHO after dual it's kind of overkill LOL!!! The duals have enough juice and they are superisolated! So be careful that you don't turn them up to high because you'll hurt your ears. Also since you're isolated be careful not to overplay. You will find yourself playing harder and that will hinder your hands. So ultimately if you have a good sound engineer and/or an AVIOM system (or any other Personal Monitor System, mixer,etc.) Then you're good! Plus you can use them for your IPOD when you don't want to deal with anyone on a bad day LOLOL!!
