I've been thinking about changing out the SS for braid on my Scottys too, but haven't really used them much since buying them 3 years ago. I have just started trying to learn the proper setup to target the silvers in Lake Roosevelt and really don't like messing with the SS.
One thing I did read on Scotty's website is they specifically state not
to use mono on their downriggers, so I wouldn't recommend that as it might void your warranty.
Big D - All you should need to setup your Scottys is some wire, fuseholders, and terminals to make connections. I didn't like the thought of the straight Marinco plug coming out of the side of my gunwales, so I nixed them in favor of the Hellas. Besides, my Scottys have the Hella plugs and I like the 90° Hella sockets, so that's what I used when wiring them to our new Hewes. Less likely to get bumped into and broken that way. I can post some pics later if you like.
Bodo - How many feet of braid would you recommend for replacing SS? I think my 1101s have 250' of SS, so my thought is I should load at least that much braid - right? I see Scotty has 250# braid and 175# braid but you mention 200#. What brand would you recommend? Any better than others for wear and abrasion resistance?
I know, too many questions.
