I'd use the 270 of the 2, because it's probably lighter.

Hey, I like that!
I'd encourage you to use the one that you're most comfy with and that will most likely be the 2.70. It'll be lighter and easier to carry and will bounce you around a bit less during practice.
One last thing, I'd forget the nonsense of taking a 130 for this and a 150 for that. Pick one bullet and stick with it and go forth and fill up an ark with it.
