Doesn't make sense to do any sets. 2 carbons = $140,000. Add in Pietroangelo, and the rest of players and Jerseys and you are at 200k which is what you can buy him for.
Well don't do hero sets when carbons are high. Normally they can be had for 55-60k or you can buy jerseys/logos/arenas even cheaper and make them. You just gotta be patient and buy them cheap. I bought 4 carbons the night before the set ended for 45k, 55k, 55k, and 65k, sold two of them for 78k each and used the money to snag more golds when they went below 6500. I started out with 180k coins from selling MS Modano and even though I only have 14k left I came away with 4 carbons and 23 golds.
Plus you can get free carbons and golds in division packs and if you complete the set you get a master collectible which may be the most valuable part of the set eventually.
