Don’t buy anything until you read this.

Then study pop reports and read as many Net54 threads as you can.
BTW - never pay a premium for an SC 350, 30!!
Regarding Piedmont, There are 11 players that are tough with a piedmont 350 back. No reason to ever pay a premium for a Pied 350 unless it’s one of these Elite 11. Pied 350 is maybe the most common back and I feel some people try to get extra value bc of the Elite 11. Even VCP has a Pied 350 section. Its total BS. Only those 11. See this thread:

Also, piedmont 350-460 factory 42 is a very tough back. It carry’s a legit premium
I don’t think any Sweet Cap deserves a premium, although factory 25 (in both 350 and 150 series) can be very tough to find.
Tolstoi and Old Mill are pretty common backs but they can be near impossible with certain fronts. Pop reports are your best bets there.
