Splash is mine and I ride/used to ride the others. Chester (the little grey) I broke in when I was little and my cousins now ride him.
I would imagine Splash could jump quite big, he's got one hell of a pop in him lol.
Used to BSJA but he's getting on now at 14
I think he's been overjumped as now he tends to rush everything and gets very anxious when jumping, although never refuses.
I have jumped him 3ft 6 but he's got the scope for more =]
And thankyou for the compliments ;)
