Just passing on a tip I picked up from a 1250 owner.

Use 8mm spectra on the traveller instead of 10mm double-braid. The reduction in rope size frees everything up nicely, and you can then move the traveller under load without too much drama.

I needed 17metres, which left about a metre and a half for the tail.

If you have the 'Antal' line driver, here is a doc I found to help service it. 240010 - part list.pdf

(And here's another tip. The rollers do NOT float! Damn. Loosen all screws, then undo the rollers one at a time and ease them out, remembering to secure the internal sleeve.)
