Stripped-down FlexSlider

Question

I'm considering using FlexSlider 2 for an image gallery on one page of a website. FlexSlider seems to use both jQuery and a ~50kB function-defining script. I'm probably more anal about stuff like this than I need to be, but the idea of using such huge files for one little thing doesn't sit right with me.

I'm thinking of just using the most basic slider they've got:

$(window).load(function() {
  $('.flexslider').flexslider({
    animation: "slide"
  });
});

FlexSlider has a whole host of other possible functions, though, as does jQuery. What I'm wondering is if anyone has experience stripping down FLexSlider (or jQuery) for this application. I could try to go through the code and take out things by trial and error, but I don't want to mess things up.

...or would people just recommend not worrying about the size?
