Didn't see head handle to shaft adjustment hole's, Plugger has three hole's for adjustment to balance the machine, and didn't see the coil on the shaft , maybe the seller's will do another video, not impressed , as we all spent money to re- mod the original to CF . PS I see a AQ copy on the coil ear's look's interesting.
I upgraded to Plugger's and find it better balanced with the armrest and handle/control pod in the furthest forward holes. His included an easy to loosen and tighten knob with no spring holes to slide the lower far into the main shaft.
I'm very happy to have changed it out for those two reasons alone.
60% higher than I paid (and I paid $20 extra for red) and that doesn't even include whatever they are charging for shipping. Mine is telescopic but I went with 2 piece instead of 3. Much stronger that way though of course, not as small.
Another big reason to do it is if you water hunt. Those twist cams the manufacturers use are nothing but nightmares as they get dirt, etc. in them.
