Hey there! Welcome to SaberForum! Most excellent choice on going with both the Archon 2.1a as well as loading it up with the Emerald driver and Obsidian sound! Very cool way to start your saber career off right.
Best of luck to you finding a group to join there and finding your niche with the new saber, or I should say
sabers... you didn't think this would be your only saber, did you?
welcome to the addiction, er um, your new hobby <nudge> <nudge>
Seriously hope you feel welcome and take part in the community here whenever you can.
