but obviously a good horse is a good horse and a great horse will carry whatever you put on his back and win--for example Dr. F ager won carrying 134 or Native Dancer in the 50's won carrying 137 for 7 furlongs

I agree that a race over 1 1/8 mile and over 121 lbs. Every pound over 121 will slow a horse by one length. The great ones will still win, but most will show that the weight did shorten their margin of victory. Races less than 8 furlongs the weight shouldn't be a factor. Weight will slow them down.
