odysseysteve,
Congrats on quitting the stinky's,,,,,,you didnt say what 18650's your running, if your not already using the AW IMR 18650 make sure you pick up 4 of these and use them, you also may want to try an HH-357 1.5ohm Atty on your Grand. Again Congrats on quitting and on picking up the right
mod from the start.
