Anybody have any experience with these TSS loads...

Federal HEAVYWEIGHT TSS Flightcontrol Flex 12 Gauge Ammo 3.5" #8/10 Combo, 2 1/2oz

A local shop has a pretty good sale on them to make room for 2025 inventory.  I know the straight #7 or #9 TSS loads are probably the best option, but would anybody recommend these if the price was right, around $5.20/shell?

I never had good luck with the old Federal flight control wads, but these are supposed to be an improvement over those??

Thanks!
