Need to up my cracker game, recommendations? What about cheese??

So I tend to use Ritz crackers or, lately, Sonoma pizza crisp (which are stupidly good)

I don't tend to do much in the way of carbs, mainly because of a surgery I had so they SUPER fill me up and can cause some pain, but open to trying other crackers!!

thoughts? recommendations?

cheese wise, I tend to do cream cheese, havarti or provolone. am I missing out on any bomb ass cheese with sardines?
