Optimizing M1 Carbine accuracy - barrel band with or without bayonet lug?

[Kabal]

I've bought an M1 Carbine made by Saginaw which has the type 2 barrel band. I'm thinking about replacing the barrel band with a type 3 with bayonet lug.

I prefer the look of the bayonet lug, and I'm going to remove the front sight anyway, so replacing the barrel band wouldn't mean a lot of work.

I'd like to use the rifle in matches every now and then, so accuracy is important to me. I've heard that Jerry Kuhnhausen's shop manual says that the bayonet lug might be detrimental to accuracy. However, this article from Precision Shooting Magazine claims the exact opposite:
http://de.scribd.com/doc/27034567/Accurizing-the-M1-Carbine

The author calls the type 3 band and bayonet lug "a necessity if you want to achieve any kind of accuracy with the carbine".

Can anyone confirm if the different barrel bands affect accuracy in any noticable way?

The general consensus is that barrel bands with bayonet lugs lend themselves to better accuracy.

Here is a good link for some reading:

The barrel band with the lug is general considered the best option.
You also want to make sure that the recoil lug fits tight and is low enough to keep the barrel up off of the stocks barrel channel.
You can usually help out the trigger pull but there isn't a whole lot you can do with it. The triggers just aren't that good in the Carbine.

Thanks for the advice, Hacker and carbine!
