Each year I buy a Topps series 1 and 2 pack and an update pack ( as well as a Heritage base and high series pack) to keep with that year's set I try to avoid "fat", "thick" and "hot" packs because I do not care what is in them. But it is sometimes tough to find packs that sellers don't deem "hot". And I myself do not know one from the other. Maybe I need or hire Justin and G as an agent for such purchases
