I like to use these https://www.amazon.com/gp/aw/d/B085HG47BN/

They are nice and big 23"x35" and cost about $0.50 if you buy 100

I then usually throw a few splatter stickers on if I am shoot a far distance

These are 3" squares and cost about 0.07 each so I put a few on each (could put 17 on a sheet for the same price as the targets you were thinking about)

I like doing this since you get a nice big taglrget overall with the outline of a body, but can put smaller splatter targets in specific areas to work on aim
