Best Showing Pedigrees

What's everyone's favorite dressage / western pedigrees? I'm looking for studs or horses for sale with good showing lines.. any recommendations? 

I'd look less for pedigree specifics, and more for low NSS (specifically base so you could convert if needed) non-specialty stats. Generally, anything 57-60 and lower will do pretty decently in shows. I primarily keep 50 and less, and get many horses to 500 places and 200-300 wins in their lifetime.
