Galfer brake line kit for my 1100 - special ordered for me by the local Cyclegear. Good quality, coated hose, with all stainless fittings, including new banjo bolts. I don't suppose you'd go wrong with any established manufacturer.
I put 1150 bark busters on my 1100. They fit just fine but I needed to buy a small adapter for the Throttlemeister. Can't say I've noticed much difference in weather protection for my hands. I did have a problem when the R/H guard got twisted around and was touching the end of the brake lever, causing the brake to stay on very lightly. 100 miles of high speed riding in the rain precipitated a binding problem that took a full caliper rebuild and brake hose replacement to cure.
