Fractured Axel

Hi all,
Having just got back into kiting with the purchase of a Stranger, I was wondering what line length (and strength) to go for.
I did used to fly a Psycho on shortish lines - say 15m. Was wondering what would be a good starting point for the Stranger?
Cheers

90lb should do, as for length that's a personal preference but for me anyware between 60-85ft.

I go 25m 75k on light wind lines and 30m 150k on heavy lines, I think that's average but as Craig said its what feels comfiest fa you.
