Sticking weights underneath your se fighstick

Does anybody know of any good weights and where to buy them. Also do I superglue it?

Get some ankle weights or something like that.

I would imagine sandbags would work well, just seal them well and put them in the stick.
not a lap player so I wouldn’t really know.

look up diving weights those would be the best thing for you. you would have to put any weights inside of your stick. anything, save for some sheet metal, would be too bulky to attach to the bottom.
