What size splits work best for even heat the size cooker?i struggled with even temps which why i bought lang firebox side could 40 deg hotter or more than right side.My splits of oak r 14x2 for 120gal reverseflow with oversized firebox so I split them in half still struggling with temps.did notice moisture coming out wood when put in firebox even though been sitting covered and split for 2 years now.should I cut them in half length wise?
