Differences between 'Sparky', 'Nescii' and 'Nesci's Gold'?

[Truth]

Hi all,

I'm planning on heading over to Rays later this week, but was hoping if anyone could give me a preliminary summary of the characteristics and differences between these three cultivars of Trident maple.

I'm mostly interesting in leaf characteristics, colour, vigour and speed/size the tree is inclined to grow.

I mostly prefer really thick and girthy bonsai trunks, so if I were to pick one up, it would be ground grown for a number of years. However I would prefer a tree that grows thicker read:(taller) faster.

If anyone has any good examples in their collection, feel free to post photos too!

Thanks!
