OK I've finally updated the OP to include the latest config for the "Laid-back" one. I've made quite a lot changes compared to the one it's replacing;
Changes:
- Quite a bit changes in Freesurround, especially regarding "Focus (Ambient <-> Localization)" setting where I went from like +0.50 to -0.26 which resulted in less sound quality impact, highs no longer metallic and the treble range is overall clearer but the soundstage is usually less wide but more natural sounding.
- Matrix mixer got all channels' volume adjusted separately for best result
- Dolby Headphone amplification went from 110% to 113%
- Minor EQ adjustments in the treblerange => more natural, closer to stock foobar sound
==> More versatail, no longer only works superb for specific recordings or genres but I'd avoid if mainly listening to rock still though

Compared to the "forward" config this is still as the name hints, more relaxed, laid-back, not as "in-your-face" sounding, now they complement each other better in my opinion so that they are similar but still different regarding the positioning/soundstage.

And finally, here's a demo with the new config
