I just completed my AOW and will be starting rescue soon. I’ve been slowly piecing together my first kit off market place and I got great deals on both regulators. I only scored one of the XT2s but two of the A700s. I plan on trying both setups at some point, but just wondering what yall think would be the best 1st stage and then should I run two A700s or put the XT2 in as my primary or octo?
