If you want hot, yet smart - take the Peppy.  I have a mare that's almost the same exact pedigree - just changed at the bottom from Leo to Freckles.  She's been a cutter, reiner, cowhorse, even a westcoast dressage horse (and did very well).  She's hauled fat asses over mountains, done most all in the local shows, and now is used for therepy riding.  She will let someone know she won't put up with stupid anymore, and if they don't believe her, she will dump them.  She also kills dogs that think they should chase horses in the field.  Great little horse.  Heart the size of Texas, and a brain to go with it.  Can do a pattern fast enough to bring tears, then toss on a kid and she barely moves.
