I thought they were scented but nothing

maybe because they're different in other countries ?
Tragically, they've gone unscented everywhere. If you're still finding the scented ones, they're old stock. The new ones still have a semi-pleasant scent when wet, but they're virtually scent-free when dry. :frown:
Pampers diapers were pretty much the last scented diapers around. In a world where parents are freaking out over every little additive, it was surprising to see them continue to scent their diapers so strongly, particularly when Huggies and even most of the store brands had gone scentless years ago.
Sigh.
I tried the Crusisers 7's and they didn't seem to stretch or hold as much, plus they seemed like exactly the same size as the 6's.
Indeed they are the same size. Like, exactly the same. Cruisers and Swaddlers use a different sizing system than Baby Dry, Extra Protection, and Luvs. It's a dirty trick. Absorbency-wise, my observation has also been the same as yours: Cruisers don't seem to hold as much. I haven't attempted a really scientific test, though.
And as for the once-legendary stretchiness of the Cruisers 7 tapes: It was spoiled a couple of years ago when Pampers added all the extra Swaddlers-style padding to it, making it much harder to stretch. At the same time, the improved plastic welding used for Cruisers was handed down to Baby Dry and the other diapers, so there just isn't much reason to get Cruisers 7 anymore. And they're hard to get, besides! Forget 'em. Baby Dry 6 really is the way to go in Pampers anymore--unless you have a Target store near you, in which case you can probably get the much-more-absorbent and identically-sized Extra Protection 6.
