If I could change one thing it would be to do away with grading. It is such a silly scam, why do I need to pay somebody to tell me if a card is nice or not? I can decide for myself. The only use I can see is for people to demand a higher price for the perceived 'value added' of a high grade...
Mine would be (in order of preference)
1. Bowman
2. Bowman Draft Picks & Prospects
3. Topps Chrome
4. Bowman Platinum
5. Gypsy Queen OR Heritage
Yes, I would axe flagship.
