yeah, it would be neat if companies could figure out a way to beat the searchers in the modern era...back when I started, searching was looking at the top and bottom card on cello packs before there were inserts and autos or relics...
I don't know how searching works, I opened a case of 2012 Topps Olympic Blasters yesterday and weight didn't mean anything, I pulled hits out of boxes that weighed 208 grams, 210 grams, and 220 grams, and I pulled blanks from the same weights...it is fairly easy to tell 'pin' packs because those are so much heavier than others, like a 12 gram difference, as I have weighed known hit packs vs regular packs...but I don't buy/sell 'hot' packs because I don't trust people...I could sell packs where I could guarantee the insert, as there is a pattern to the boxes in the 2014 Topps Olympic for the bronze and silver parallels, but with my luck it would also contain a huge card...
