My question is, do Ice Climbers really need another move that slides around and cancels into grab? What does Squall Hammer do that Blizzard doesn't? (Besides go into the air, that is.)
I'm definitely not saying they need it, I just wanted to see how it would work. And It's certainly not like this only buffs their side-b. Popo can grab out of d-tilt and u-tilt, too. And if you jump-cancel grab out of shield, Nana does an aerial. I still plan on testing this a lot more, but it certainly gives ICs a nice few new options without totally breaking them.
And allowing SoPo to grab out of side-b has certainly proven to be very useful, too.
Edit: I'd also like to add that grabbing out of side-b via the jump-cancel allows for Nana to act out of it, whereas with down-b you'll oftentimes find that Nana is still in the middle of doing her down-b when Popo grabs. It's a nice little addition that doesn't amount to anything too much, but it's there.
