Cool, Ian I would love to read some report! just realized Airlfo has a very similar product (a bit longer, but similar taper and interchangeable tips). The Tactical Steelhead Line description from the Rajeff sport website... Take the tight loop and casting ease of a Scandi Compact head and couple it to the versatility of a multi-tip line and you have the basis for the Airflo Tactical Steelhead shooting head. To help cut through the wind and to make casting modest sink tips and larger flies easier, the Tactical Steelhead has a larger tip diameter than the Scandi compact. With a smooth front taper and removable floating tip the newest two-hand line from Airflo will convert from a floating line to sink tip better than any existing line. This new head will change the way many people fish.
