GFX or BL35
 

I have been racing elec rc cars for several years and am finally upgrading to a CE charger.....what would be the main advantage of a GFX over a BL35 at the race track....not so much any bells and whistles, just things that a racer needs....

thanks in advance Gary

also would the pit bull make a good secondary charger, and if so, what amp power supply would I need to run them both?
