[LAU] Favourite Linux reverbs?

Hi all, since the combination of Tracktion 6 and Carla as a VST plug-in works reasonably stable, I started to record and mix more and more on Linux (Arch) but I'm still not very familiar with the choice of good plug-ins available and how to get the best of them. So, let's start with reverbs: which reverb plugins do you use? Which are your favourites? In which situation? Do you have any good settings or presets to share? I can use almost any format, i.e. LADSPA, LV2, Linux VST, Windows VST 64bit, although I prefer LV2 and Linux VSTs and at least a basic GUI, since I like it when parameters are labelled properly and have "real" values, not only 0.0 .. 1.0 ;) Tracktion has a very flexible routing system, were you can make every track an aux bus by inserting an aux send plug-in after the source track and an aux return plug-in before the effect plugin on the aux track. This makes it very easy to pre- or post-process the reverb signal with other plug-ins (e.g. EQ or compressor), so to my purpose it doesn't matter if a reverb pug-in doesn't offer many parameters (e.g. built-in EQ etc.) as long as it sounds good. Looking forward to your opinions and ideas! Chris
