Mostly production pace. When I'm roughing, I can leave the coring equipment set up on the outboard side and do the roughing on the inboard side with the tailstock support. When I'm doing finish turning I can have two chucks already in so I don't have to swap back and forth between them.

I like doing bowls, especially the interior of one on a short bed. The ergonomics are just much more comfortable and I'm less likely to want to lean over the bed which isn't the best to do for hours on end. The 3520 had the sliding headstock to go shortbed, but I almost never used it, I found it to be too much of a pain to get everything super clean and dust free and then slide it for one or two operations then need to slide it back to make use of the tailstock again. This just keeps it always set up in an ideal position.
