All rigging wires top and bottom (except luff lines.) 

Your glider might have other rigging wires that are not included in this price but that should be changed. eg:
Tension wire.  This is the wire used to pull the cross tubes back.  This wire is heavily used especially on a glider with a VG. It is well worth replacing.

Some aircraft have VG systems that operate with a system of rigging wires pulling a leaver connected between the leading edge and outer end of cross tube.  These wires can also be replaced if required.

This is the best method of replacing wires.  Many pilots prefer to replace just side wires or lower rigging to reduce cost.  Top rigging wires are not loaded much in normal flight.  Though failure of these on landing can result in very expensive repairs.

If you replaced just your lower rigging last time then perhaps now is the time to replace all your rigging wires.

Pilots often worry about replacing rigging wires before they have got their 'full monies worth' from the old wires.  Clearly the only way to get 100% of the life is to wait until the wire fails.  While this could save you money on wires you could end up paying a very high price in other ways.

A far better way to view wires is as something you want to replace before you have got your full monies worth.  This is more expensive but does make for a safer hang glider and less worry in flight.

Clearly judging when a wire should be replaced is a difficult thing to do.  If they are corroded, kinked or damaged in an obvious way clearly they should be replaced straight away.  If apparently in good conditon theyn the age of the wire should be looked at and the BHPA recommendation for annual replacement born in mind.

Don't be too mean with wires.  They are not expensive, especially when the cost of failure is considered.
