Tonio. i've been using a standard rear shock all season - it aint perfect but its not bad. Set sag to approx 5mm and start with standard damper settings.
1st thing to change on the 620 are the front fork springs (the standard ones are horrid dual rate things) to a single rate spring (Neil at Sigma might be able to advise on what weight spring (can't remember what i'm running)). Use 7.5 weight oil and fill to standard air gap. After that you need to play with spring weights / air gap - aim for soft as possible without it bottoming under braking. I've dropped the yokes down the forks by 10mm but you're best starting at standard.
