Do you stow your lazy jacks?

[Sabbatical II]

My last boat had an excellent lazy jack system fitted by a local sailmaker. It had a line for each side of the bag and the whole lot could be stowed at the mast when sailing. The bag stayed upright on the boom when sailing and if I needed to drop the sail it was a simple thing to uncleat the lazy jacks off the mast and re-tension them for use. The system on my new boat is not so user friendly and I can't easily stow them at the mast. My question is: How many of you just leave the lazy jacks up and has the chafe damaged the sail at all?
