Thinking of getting a second bp with an 801 connection, but was wondering about the draw. I have heard that the 801 cap has a tighter draw and I am liking the draw I get off the 510 with and 801 adapter. running fusion exclusively on the 510 bp and like it. hoping to get the same out of straight 801 connection. I have also heard of the slotted screw swap to improve airflow. Does it work, and is the draw the same?
