i've tested the new vert maxflow against the old vert maxflow. the performance on the new maxflow was a bit disappointing. the new maxy has a poor recharge rate, but it's very consistant. imo the old very maxflows are better, recharges faster and is just as consistant. i would rather have a bigger but better performing reg then a small but poor performing reg any day. i will not be giving up my old maxflow any time soon.
