It seems nearly everyone is collecting them:
these proofs of use or the evidence that the retriever line can be a nasty bitch in burning tiny little holes in the bottom part of your spi.

this seems to be mainly related if you lower the spi on that side where the retriever line would be running outside the spi and therefore runs back over the tissue to get the spi in. I think I have seen them now nearly on every snuffer used spi so far, and it seems that a clean, fast and therefore very smooth dropping of the kite is the only chance to avoid those holes... I am pretty sure that systems who seperate up- and fore-holder might not have this problem, but who would seriously consider an otherwise smooth running one line system for that? so any tips from you guys? silikon spray on the spi might not be a good idea, as repair tape wouldn't stick any longer and spraying other parts like ring (original AHPC alu-ring) or rope did not help much... a special material retriever line (which wouldn't get that hot maybe??
