What popular items to keep an eye on in CS

I have recently tried to start merchanting and am currently tracking the prices of the following sets in the CS:

- lvl 55 RR, FF AND MM
- lvl 55 sewer king, royal sewer and sewer queen
- lvl 50 ("of") death, hate and shadows
- lvl 50 ("of the") void, rift and cosmos
- lvl 25 crystalline
- lvl 25 earthquake
- lvl 25 onyx
- lvl 5 twinks (blacksmith, armsman,alchemist, sorcerer, artisans, expert)

Apart from the above sets, I was wondering if all you merchanting experts out there could share with us what other items you look for to buy/sell ?

Thanks in advance

Voodoo gear, level 45 pinks from ao3, shivering gear, fishing poles, xmas items, level 51 sewer pinks, doom weapons, lvl 21 sandstone sets.. to name a few

I asked my friend earlier and he said hate armor is pretty popular right now.

You might also try posting in the Traders Market forum, since that seems to be the place the merchants meet. :)
