I have a SGC master set going but it has slowed to a crawl.
I have not added any new holes but have upgraded some this year.
I have a few more to send in to get graded...or I will just seek those already graded since the raw ones I have are low grade.
I have primarily mid grade commons (SGC 40/50/60) and low grade stars (SGC10/20). I love the way they look in the black slabs.
I have a really good start on a second set, maybe 35-40% but I don't know if I am serious about doing it again. I probably will since this remains my all-time favorite set and I tend to hoard my favorites

I might collect a low grade raw set too, since they look great all together.
With the ~ 260 or so slabbed cards I have in this set, it takes up a lot of space and weight. The raw ones I have are in top loaders and are in a small box, that's appealing in some ways too.
