thank's for you report!
My descent cable is about 30 meters. An old LNB plus a very long descent are a very bad pairing.
I looked at the BLAK ULTRA 1 exit because they give it a suitable fit for long descents.
Seen then the cost very affordable, I think it is a test, which at this time I can do.
Of course ... then there is all the alignment ... but right now, with the temperatures I find on the roof ... I'm not on schedule! Maybe in September I'll make the passage to LNB
Thank's again to all!!
