Personally, I would avoid buying the ones that were used for slacklining purposes. The loads put on the anchors points of a slackline are much greater than what would be experienced in a fall. For example:

60kg person
10m slackline
sag of 0.9 meters when person is on

Force on each anchor = 3.4 kN PLUS pre-tensioning used to tighten line (conservatively, say 4:1 with two people pulling hard is about 1kN)
TOTAL: 4.4kN
-Not considering heavier or multiple people, or dynamic loads.

A tighter slackline under the same conditions that sags at only 0.5m

Force on each anchor = 6kN + pre-tensioning
Pre-tensioning would be greater to achieve less sag

Even if two cams were ideally equalized on one side the load are relatively high, sustained, and frequent.

If possible use a tree when rigging a slackline.
