If you do get some, I wouldnt bother with the thinnest or the thickest ones. You say you want to get the light ones? Those are thin. These are almost useless and you'll regret wasting the money. And the thickest ones are less useless but too clumsy too use, they give too much resistance/assistance depending on the use. I found the most useful ones are the middle ones. The ones I got were yellow (thinest), orange (mid thickness), blue (very thick). I only really use the orange.
