I'm kind of curious myself. I just got my TG5 and Oly housing moving up from a GoPro. I'm bring my RGBlue Series 2 PC video light with me and I just purchases an INON z330 strobe. I liked the look of the YS-D2, but there are so many reports of issues and I'm only going to have one for a while. I'm getting a MIC21 tray and arms setup (local brand) which looks solid. i debated some on getting a second video light, but it just wouldn't compare with a strobe. I have some friends who are doing quite well with one, and with the upgraded power and wide angle it should work well for me and I can add another if/when I ever decide I need one. Reading some of the posts on people downsizing I'm glad I didn't go with my E-M1 for now and put the money toward lighting.
