Im really stuck in between some horses.Im stuck between the shire,swedish horse,thoroughbred,lusitano,and connemara.Which horse should i get in the future since im still saving up.I really cant decide,they are all really good horses!Thanks!
For racer's since none of the horses have speed mulitpliers, you are going to want to focus on horses with great agility and strength. Of the horse you have suggested:
Shires have a bulky model which can make it hard to move around in a race and their recovery animation is pretty slow on top of that while they make good jumpers (with a 5 in strength) they have no agility stats.
NSH's, both new models and old models, like the shire, do not have any base stats in agility, so they won't be able to turn as quickly as other breeds.
The English throughbred, while it has high agility, it only has 1 in strength. This is an easy problem to fix if you are careful about jumping and avoid unecessary jumps in races in favor of shortcuts.
The Connemara like the NSH has a high jumping ability but only 1 in agility which can be a hindrance, however unlike the other breeds, the connemara can also race in the pony championship, and currently has the best base stats out of all the pony breeds.
The Lusitano is your best bet of the breeds you are considering. It has a 3 in strength and a 2 in agility, plus a 2 in discipline in the off chance you need to change gaits in a race.
Of the breeds you did not ask about, many tend to choose the New model Appaloosas/APH's because their model has the fastest recovery animation on top of having decent base stats. But a well trained player can easily win on another breed without relying on that extra milisecond.
It should be noted however that while breed base stats can help you buff up your ability. It really comes down to how well you know the shortcuts in races and the tack you wear, so I would also focus on studying the tracks and investing in gear with high speed/riding stats.
