Can we talk about how I swore off cheap paper for proof sheets, and then a supply guy at the shop on 5th set me straight | CMYK Console Crashers - The Design Community Hub
Sounds like the supply guy saved you from wasting money on fancy paper for no reason. Think about it, proof sheets are just for checking exposure and focus before you commit to a real print. The ink and the press matter way more than the sheet you test on. Spending extra on thick paper for something you toss after one look is just burning cash. Cheap paper does the job fine and you keep more money for the stuff that actually shows up in the final print.
