Haven’t really used a rolling tray since I was smoking seeded brick weed (not as long as you might think). A good tray would have a decent lip to it to prevent the seeds from rolling away. A cover would be a bonus, so it is inconspicuous.
What I prefer are stash boxes. Something nice that you can keep on the coffee table, yet still store your paraphernalia in it.
My dad was making kief boxes for a while, that’s what I use now if I ever decide to roll one up. It has a lid, then a stainless steel mesh screen. Under that is a little drawer with a piece of glass on it to collect your kief on.
