I have heard, and liked that table/arm combination. This is a well behaved combination that does a good job of damping resonant energy from the cartridge tracking the groove (as evidenced by how well it damps large, sharp impulses such as ticks and pops; they are less obvious than is the case with many other table/arm combinations). For some listeners, that kind of behavior is considered "dead" sounding, so taste and system synergy issues matter when it comes to whether this is a very good combination. A local dealer who usually hates well damped table/arm combinations likes this combination, so it is not extreme in this respect.
Others have discussed the various tradeoffs of longer and shorter arms so I will only add two more points--the longer arm will mean less variation in vertical tracking angle/stylus rake angle when changing records of different thickness. I don't fiddle with VTA/SRA when changing records, but, I do know from experience that even small changes do affect the sound, so in this respect the longer arm is better. The longer arm also means a smaller offset angle of the headshell and correspondingly less skating force. Because the skating force is not zero, antiskating is still required, but, less anti-skating is required and so issues with skating/antiskating is reduced a little. With newer materials and technology, the rigidity/damping behavior of longer arms has become less of an issue than in the past. Still, there are many designers who think it is such a high priority that they favor the shorter arm lengths. I've heard enough good examples of both lengths used in arms from the same manufacturer and I don't think it makes that much difference.
