Favourite convolution reverbs/impulses for rooms/early reflections

[chagzuki]

I was just recently finding I was getting a better results using Space Designer in Logic to add cohesion to electronic drums and sit them in a space that doesn't blur or smear them, rather than the algorithmic reverbs that I've been favouring for most duties. Weirdly, I think Space Designer might actually be causing crashes in Logic, but anyhow it got me wondering what other convolution options there are for that purpose. Perhaps there are some specific free impulses that peoples are finding particularly good? Are the dynamic systems like Nebula going to add anything to reverbs not based on mimicking chorused algo hardware units, i.e. real spaces?

I did have Waves H-Reverb, but I hate Waves so much I don't even want to install the manager on this machine. Maybe I should take another look at it.
