Wow. I must have gotten lucky, because my 'pantin' (if it truly is pantin) is not even 6 feet tall, yet it's on its second crop. First crop consisted of 5 - 6 fruits. It's either not a pantin, or the rootstock is dwarfing it, because the tree is 7 - 8 years old.
My pace, on the other hand, looks similar to your pantin and hasn't yet produced.
