Does anyone know if the Dart BigM is worth the extra money over the Merlin block?

Also, if you know where I can buy one cheap, let me know!

The Dart Big M is all over the Merlin II. I was considering the Merlin race block with the steel caps and decided on the Dart M in the end.

I found that Flatlander Racing has them at a good price, and they claim...
