Some time ago we discussed and perhaps failed to resolve the dilema of mending short heavy head spey lines without pulling on the fly and causing it to lift in the water column.
It is always difficult to know what has happened ,because we are unable to see the behaviour of the fly to know whether it is lifting or not.
I believe that when we try to mend a heavy head with a light running line we inevitably create tension in the line causing the fly to rise.Indeed I know no other way except by creating tension we can lift a heavier object with a lighter line. I know that Per for example disagrees with me on this and is sure that he can mend such a line without tension.
I suggest that the most practical way to determine whether the line is pulled or not is to use a floating fly ,perhaps a Mirimachi Bomber and having cast straight across stream with a windcutter or similar line attempt to make a mend with fully lifts the heavy head down to the leader;and to watch the fly carefully .If ripples occur around the fly it is a sure indication that tension was applied to the line and the fly was drawn forward. If it had been a sunken fly it would have risen in the water possibly taking it out of the strike zone.
How about it Per tell me what you see when you try this.
