Hi. If you are able to afford a sound saber then the Champion level definitely will take your saber to a whole new level. You have instant access to changing the blade pulse flicker, sound intensity, swing intensity and clash intensity. All this without needing a computer hook up.
Suggest that you purchase the 12w LED as it is super bright. Since it comes with a covertec wheel get a belt clip if needed. Since you have a Jedi colored blade you will be getting Viridium sound unless you choose the Crimson dark font when ordering. The 37" blade is not too long to manage but the 32" may be more comfortable if you are not tall. There will be some length taken in the emitter. Your chosen saber will look really good.
