I was looking at the options of adding weight to my crystal flowlights and I found that I have two options.
There is the weight sleeves from HOP
Link to them Here and there are also the Flowmass from flowtoys
Link to them Here The weight sleeves add about 35 to 40g to the poi and the flowmass adds 28g. The weight sleeves cover the whole poi while the flowmass covers the end. I have also noticed that the weight sleeves are clear while the flowmass is white.
I was wondering if any of you had suggestions or help on which one I should get.
