Am I the only one who's a bit disappointed when using the Simrell Extraction Chamber with the Woodscents? I've never been able to get my material to extract evenly with this (always green left on bottom), and/or a stir always seems to be required. I believe I've tried every different combo of pack, volume, etc. and always seem to get the same results. In contrast, while standard DV tips hold less (only knock there) they've consistently evenly and fully extracted my material - without the need to stir. For those with a different viewpoint on this, I'd love to hear what helps the chamber work well (i.e. loose/tight pack, use a straw pack/don't, etc.)!
