Yeah, recently got a CW Computron, decided to get the Toyhax labels for him, and used maybe about 75% of them at most. Left Scrounge nearly untouched as his labels just made him look busy, but added some to Cybaxx or whatever they want to call him, becuase there was just too much yellow on such a small figure, but only about half of them, becuase otherwise... yeah there is too many for something that small. I think Lightspeed is the only one that I used all his stickers. While he's still my least favorite of these, he looks ALOT better.
I'm not a painter, my attempts never look that great. So I'd rather go the toyhax route, but I have to consider each set I am interested in and if they are worst the cost vs what I feel I'll use. Like I said, it feels like some sheets they need to pad out the sticker count to justify the cost of printing them.
