Mega Arbel advice

[G_Dubs]

We're doing our first Mega Arbel job next week and I'm looking for input of the pattern.

A friend of mine who uses them often tells me what a bear they are and that the pattern is really tough to figure out and keep correct throughout the job, but my local supplier told me today that there is no real "pattern" and to just lay the cloverleaf configuration without putting the same pavers to close to each other.

Opinions? Is there a definite pattern to stick with, or do I just lay them out and keep the joints random?

Thanks
