Anti skate and tonearm damping query

I have read a number of threads relating to both antiskating and tonearm damping on the JMW 9" Sig.arm and find myself a bit confused.......I have been experimenting a little and have reached the conclusion that I must be deaf. I have not used the additional antiskating system, I have tried twisting and not twisting the leno wire and can hear no difference. If the Leno wire is not twisted therefore no antiskate, will this damage the stylus or the album??
I have also filled the damping well above the taper to the base of the point and still cannot hear 'the music being sucked out' or indeed, an improvement. Do I fill the well up to the point!! and then work backwards. Those that finetune using the damping seem to have some sort of epiphany when the 'sweet' spot is reached.

Can someone please shed light on how I should be going about setting the AS and finetuning the damping on the arm. The table is a scoutmaster with super platter and sds, the cartridge is the dynavector Te Kaitora Rua

Thanks

I actually do not use any with my 12.7 or JMW 9" arms. The amount suggested is often wrong and it is impossible to apply the correct amount all across the record. When I do use it I try to use as little as possible. Use Denon 304 on the 12 and 103 and AT OC9 on the 9".

IMHO the wire on the Signature arm is to stiff for the twisting method to work. I use the VPI anti-skating gizmo with just a bit of anti skate applied and no twist of the wire either way.

Thanks to all for the advice.............I have read that the damping fluid is ineffective unless it is actually in contact with the internal part of the tonearm that sits on the pivot point is this correct? Thinking about it...........this does sound logical, However, it contradicts most of the other comments I have read about damping fluid.

In general - "skating force" is not linear. It is general with modern styli much less than it used to be in the 1970ies. Several respected tonearm designers (Pierre Lurne, Mortensen, ...) do recommend not using anti-skating at all and for good reason - applying a steady and linear "anti-force" upon a non-linear force is not a good idea at all......

Dampening - if you REALLY need it, the cartridge/tonearm match is less than optimal in terms of its mechanical parameters.
In general - less is more with both issues.
If you apply any dampening fluid, do use as little as possible and do use fluid which is NOT like honey but more like water......
If you apply antiskating at all, do set it as little force as possible - 1/2 of what is recommended by the manual will be enough and more than that.
The higher the VTF - the lower the antiskating !
