Who should I breed my mare to??

Breeding my Appaloosa mare has been a dream of mine since I got her when she was 6 months old, she is now 8 and doesn't have a show career.. but is fantastic to ride, has amazing colouring and hall of fame bloodlines on both side. I was planning on breeding her last season but nothing was working out for me so I decided not to. I had the stallion and breeding contracts in my hand ready to sign too but I decided not to. Which Im glad I waited because I love riding her, she is a 2004 15hand appaloosa mare which I ride her English hunter/jumper. A few sires I have in mind are:

My little Secret:
2009
15.3hand bay with white blanket appaloosa stallion, standing at Char O lot ranch.
Stud fee:$1000
Saudi Arabia prince owns him
3X world champion already, his grandsire "The Secret" is also syndicated

Acore:
2005 16.1 hand
Bay canadian warmblood stallion
Jumper/Grand Prix

Westporte:
Westporte is an imported Hanoverian, standing 16.3 hands, dark bay, has competed hunters, jumpers and has produced some fancy hunters and champion offspring.

There are many others to choose from.. I definitely want to breed her to another appaloosa to see what I get, I have a few foals that I want from her also to continue her bloodlines. My search will continue....
