I've never been there for schooling, only for competitions but not sure how good it would be for lower level schooling. I take my boy up to Boomerang, really like it there plus it's only up the road for me!
I would agree with poster to said there are more bigger fences than little ones. I took my lad there and the smallest they have is about 2'6 - but most of them are 2'9 +
Went to Tweseldown today, it was so busy, 90% of the jumps are open, i found a alot of jumps were 2'ft upwards and loads of jumps there.. the going was good. you can take your pick, jump as much or as little as you want.
