I ended up using all 40g leads on a 10g cartridges and with 2.5 g tracking
the lead mounted on the outside of the I-beam and the rood pointing inwards the I end up mid on the I-beam scale.
As kids, the teeter totter taught us good physics lessons. Remember trying to ride it with an adult. They had to sit up in front of the seat closer to the midpoint of the beam. It was no fun this way. Even worse when they did sit in the seat, were in control, and were nasty and jumped off quickly, allowing us to fall to the ground fast and hard.The teeter totter is the most fun when both riders are on the end of the seats, same weight..
Option One
Start losing the bodies (lead) off the end of the plank, to get to the highest number on the I Beam. This is documented in the manual. This will give your cartridge the highest vertical inertia.
Option Two - preferred.
Get the new long I beam, and with the help of physics, you will need 1/2 the lead or less, to attain the same result.
My XV1 is 12.6 grams.
