Record weights, mats & dust covers?

In preparation for the arrival of my Raven AC I was wondering if any of you (especially you Raven owners) use a dustcover?

Also, what (if any) record weight do you use??

Finally, (again for all but especially you raven owners) do you have a preference on a record mat? I am getting a record mat that can be used on both sides (just flip it over( and I plan to listen to it and decide) but would like your comments.
if the manufacturer does not offer these things there is usually a pretty good reason.
