hey melo do you know, besides sheik, who else gets chaingrabbed by dthrow -> dsmash...........and do you have any tricks to how to time the dsmash? Well, it is possible to chain grab anyone with Ice Climbers, of course it's really hard to do against, say, Samus. Heavier characters are naturally easier. But to chain grab the harder characters, do the SHDAIR with Nana thingie. This of course being when you grab with Popo, beat the opponent a little, than right as you throw him/her down, have Nana do a short hop to an immediate down-air. If you time it right, the second your opponent begins moving upward, Nana will hit him/her down to the ground (or at least stop their movement before they get too far up). But then you have to be quick to grab the opponent again.
I assume you mean downsmashing while the opponent is grabbed, so they don't go flying. For this I just hit with Popo and quickly flick the C-stick down. Almost always does the trick for me.
