The reason I was contacted about a trade is because the World block is a MP piece with the Mopar part number. And the Indy block will be a new one ordered to spec. I may need to kick in a buck or two depending on how many extras I decide on, but basically it would be a straight up trade. My new in the box World iron for a new in the box aluminum Indy.

For me, the only advantage going in is the weight off the nose. That World block is HEAVY! I don't really have a need for aluminum other than the weight. And I just wanted to make sure that I didn't make myself more issues than the normal ones associated with a Hemiroid by switching to aluminum.

So far, it sounds like I may pursue this. Thanks for the input guys, I really appreciate it.
