If the VPI 17 is anything like the 16.5 it’s a no-brainer Lew.
The VPIs tend to be multi-groove whereas the Loris are focussed and do a much better extraction job. They are also reasonably quick (although possibly not quick-er... ;^)
(At the same time I freely acknowledge that the VPIs are excellent machines and do a first-class job!)
