RK - Further I now consider an oil trough to be manditory for this rig.
After some tweaking I am getting excellent results with the damping trough. When I used it years ago I was obviously slugging the paddle through too much oil ! I am only using 1 CC per Bruce’ instructions.
Bruce is clear in the damping trough documentation that the damping trough should NOT BE USED until one becomes familiar with the operation of the ET2 and ET 2.5 without the use of one first. The added benefit I find is the visual confirmation of levelness in the trough. , as the oil in the trough is obviously affected by gravity.
Richard - I don’t like words like mandatory and absolute in this hobby. What we are creating is make believe really? This is why I like to use words like Winnie the Pooh and Goldilocks in my system page :^)
