Jason, the vast majority of tonearm and cartridge manufacturers disagree vehemently. Although skating changes across the record arms with anti skate track way better than arms without. Anyone can prove that to themselves with a tracking test record. Turn off your anti skating and the right channel will miss track long before the left channel. Fact of life, can't argue with it and so forth. Most of us would never consider an offset arm without anti skating. There is a good reason FR did not survive. These arms are antiques and should be treated as such. Put the in a glass case and look at them once in a while.

Companies like VPI have tried to sell that idea and failed. Every offset pivoted tonearm must have a method of applying an anti skate force equivalent to 10% of the VTF. Could be a hanging weight, a spring or opposing magnets which I think is the best as there is not friction and the force is very predictable. I am not a fan of any S shaped arm with a removable head shell. The inertia is too high and they have a hard time following undulations in the surface of any record. The cantilever winds up following the undulations converting these undulations into an unwanted electrical signal. I have seen oscilloscope traces of this happening. 

When I saw these traces I understood why someone would prefer a shorter arm and sold my long one. Long arms look cool but IMHO and the opinion of others like Michael Fremer are a bad deal.

Again, 9-11% of VTF is the consensus of the best average anti skating force. Tonearms that have calibrated anti skating use this figure. However, many tonearms are not calibrated. In this case the OP has to make his own weight so he needs to have a way to figure out what exactly he is doing. The WallySkater is one way to test for this. The other has not been marketed yet but if someone wants to copy it for themselves I have no objection. I call it the Gizmo. ( My wife wanted to know what I was doing. I told her I was working on a gizmo.) You can see it on my system page. It has been updated with a permanent digital gauge. It takes a direct measurement of the anti skating force just like you measure VTF except horizontal. 10% worked well according to all my test records which are supposedly overmodulated. The degree of modulation is less important than VTF as a contributing factor. This is also measured at the rim of the record where skating is at it's highest. Good anti skating devices diminish force as the arm moves towards the center of the record. The OP could use a test record to set his arm up. The Hi Fi News Analog Test Record has three anti skate tracks. Use the one that is less modulated. Use the highest modulated track to get the idea of what you are listening for. Defeat the anti skate and listen to this track. The right channel will distort like crazy. The idea is to add anti skate until either the distortion stops or becomes about the same in both channels using the lowest modulated track. This is the cheapest way to get in the ballpark.
