Arrows for Morrison: carbon help

[Red Boar]

I have a Morrison Cheyenne on the way in the near future.  I will be drawing 48 to 50 lbs. at 27 inches...thinking about 28 inch arrows.  I was going to try some Beman MFX Classics with 210 gr. Silver Flames up front.  My question, .500 or .400 spine?  Thanks in advance!

BTW: "A" riser and "B" limbs...think that makes a 56 inch bow.

Also thinking about the Grizzly Stik Sitka's...would that be a better choice?

500's should work good with that weight head

I've got a Morrison Shawnee w/Dakota Limbs that LOVES the Grizzly Stick Sitkas...I also have a Thunderhorn Heartstopper that loves those Sitkas...The Grizzly Sticks are the first Carbon arrow I've really liked.  I usually end up going back to wood, but I REALLY like Grizzly Sticks.

I have a #50 Morrison and use the MFX500.
They shoot great.
