How to attach them to the Hasselblad?
I could always use the supplied velcro but seems I won't be doing so much of tripod/strobe/studio work, most of the time the wizards won't be in use and so the velcro would be annoying.
Any ideas apart from tying them with an elastic band?
I have a PME 45 prism, so my PWs go in the hotshoe with a small sych cord to the lens. If you don't have a prism, you'll need to get the removeavle hotshoe that goes on the side rail (look at the LH side of the camera body) of the body.
