For the climbers:
Hexentrics set 4-10

Stoppers set 4-13

These are nice as wired rather than roped, and colour coded.
I'm right for stoppers, but as my hexes (I had 5-10) are the old roped variety with ~6mm holes you can't get spectra or gemini cord anymore and my cord (spectra) was purchased in 1991 (ahem), so very due for retirement.
Combine with cashrewards or shopback for extra 5 or 6%.
