Other things being equal, it makes sense. But when are other things ever equal? Even two versions of the same Pulse RDA perform very differently in terms of airflow. The Pulse works so well because it's small, but there may well be big deck designs and builds that work even better, over all. Currently vaping e-juice from a big, parallel tri-braid/clapton coil in the Pulse 22. With squonking, it's the best e-juice experience ever. By all means, play with your old toys! That's what's fun about this hobby.
