Chop Follow up

Hi Guys,
So after some practice, despite the fact that I use an aggressive looping setup  (inner carbon with max rasanter50 and 47), I have learned to play some very decent chops against topspin loops.
But I have some questions on how to make this useful:
1.) I cannot play this when someone loops very hard/fast, so if I am back from the table, what is the best shot to play instead?
2.) I have noted that it’s difficult to play this shot 2 x in a row.  So if they are good enough to loop my chop (many people choose to push because it’s so heavy, and still dump it in the net), then when I try to shop it again, I am often not successful and the ball drifts long.  What should I do on this second shot?
3.) When I get a push response, 2 scenarios tend to occur:
a.) a ‘successful’ response, like a push that floats high and mid-table that has some underspin, but is not super heavy, I step in and try to put it away (usually with my backhand).  But unfortunately after having ‘won the point’, I often end up losing it because my smash drifts long or in the net.  I struggle to decide whether to hit the ball more flat like a topspin drive or loop over the top – it’s awkward because the ball is often a bit higher
b.) I get a super heavy push (simply due to my chop, not their action) and I end up pushing it and we are back to a pushing rally.  Should I try to loop this or be more patient and build up again?
