It's funny how trooper variants were one of the coolest things about OT collecting but then came the endless (and aside from a handful of cool designs) PT clones that were pretty meh, partly due to sheer volume.
Then came the ST trooper variants where nearly all just seem so meh both by over-saturation and design (one key design issue for me beyond the cute duck-bill look is the "fat" look of the armor, which is unique in SW troopers) - and they sit pretty much everywhere unsold, years later. I recently counted nearly TWENTY different ST troopers (counting two-packs as two figures) still sitting in stock at popcultcha, which is just insane. Who would think Star Wars troopers would be peg-warmers?
Solo and RO were the only non-OT movies that to me produced some very cool looking and worthwhile trooper variants (that felt like they could have stepped from the OT,) even if I'm not a fan of the "reboot" they did to the stormie armor/helmet in those movies.
