Another vote for the Cactus V6 system here. I use a V6 trigger on camera and two or three Cactus RF-60 flashes on stands (e.g. for first dance at a wedding). The RF-60 flash has a V6 transceiver built-in. One very simple but genius feature of the RF-60 flashgun is the 1/4-20 socket on the side of the flash. This makes it possible to mount the flash directly to a tilting lightstand spigot (or any other mount with a 1/4-20 male fitting), without having to use a cold-shoe adaptor. It's much more secure than a flash sitting on top of a receiver on top of a cold shoe, and when shooting with umbrellas it means that the flash body is close to the axis of the umbrella, placing the light source in the middle of the umbrella instead of off to one side.
Cactus have just released a V6 II trigger which promises HSS - however it doesn't seem to mix well with the V6 Mk1 triggers so I am staying with the V6 Mk1 for the time being. Regarding the issue of the V6 overhanging the shutter speed dial - yes it does, but typically with off-camera flash you don't change the shutter speed once set, so I set the shutter speed first before mounting the trigger. If you do need to adjust the shutter speed frequently you can switch the shutter speed dial to T mode, and then one of the control wheels (front on X-T1, rear on X-E2) can be used to adjust the shutter speed.
