Camber links , High or Low on dex210 V2

[FLINDERSMAN]

Just wondering who's experimented moving there links up or down on there V2 and to what effects it gives.i know it alters roll centre but not sure when or when not to do it.
Ive messed about with camber link lengths that have given me better performance for different conditions. So any tips from someone with good knowledge about changing link height would be appreciated.im more or less running standard book set up with 2mm washers under front link and no washers under rear link Thanks
