That's not to say I might not try to modify the tensioner some time in the future to see if I can get it to do double....
You should still be able to use a double needle even though there is only 1 set of tension discs. I have a 158.1941, with only 1 set of tension discs, and the manual mentions the use of a double needle on the needle information page.
