Like that horizontal t-track pottzy... 
Been a great fan of those Rockler auto adjust clamps... however, have changed allegiance to the new TSO/Bessey hybrid... Was gonna do a review till LJ stuffed up their review process... however, can foresee too many poo-poo them due to price and lack of you Yanks adopting the 20mm MFT style tabletops.
Lucky the Yankeeland based TSO is not racist and have adopted the Fe$tool 20mm metric concept.

If your first cut is too short... Take the second cut from the longer end... LBD
