Gday 
I picked up my new 15" MF DD WOT coil today
Over the weekend I made a counter-balance for the coil which works well.
I found a piece of tubing which fits very snuggly inside the back Xterra tube behind the elbow.
I sealed off one end with a copper plug and dropped some lead and rapid set mortar down the tubing and then sealed the other end also (round head bolt)
Then I found a rubber chair leg cap which fits over the tube
This tubing fits so neatly inside the Xterra that it will stay there on its own but for added security I taped some velcro to the Xterra and some to the counterbalance tubing
I guessed the weight about right and practise swinging in the garden it seems great
Easy to remove it again when required and pop the standard tube plug back onto the Xterra when using other coils
