I think your Satori will like .800 spine shafts, and 100 grain points. In the Gold Tip Ultralights, that would be a .700, because they don't offer an .800, but that's close enough. For a 28” DL, you should cut the shaft to 29”. If you go with Victory VAPs, you can get a .800 spine shaft, and. 110 grain glue-in point, which will be approximately equal to a 100 grain point plus insert in the Gold Tip. The Victory VAPs are the better choice with your setup, but they are somewhat more expensive and not as versatile as the GT's with inserts.
Your choice will be between shooting off the provided shelf rest or putting on your own cushion plunger and elevated rest. I went with the cushion plunger and elevated rest for a while until I got tired of it, and now I’m enjoying the heck out of shooting it off the provided shelf rest.
