I played around with different tap&hold durations (how long you have to hold before it registers as a hold rather than a tap), but I just couldn't find a duration that matched my rhythm. I kept getting holds when I wanted taps (for short durations) or vice versa for longer durations. My current config uses tap&hold on two keys (home and end, which I don't use often anyway). Holding leads to "hyper" and "meh" which are two extra modifier keys (like control or alt/option/meta). I'm an emacs user so extra modifiers means I can basically store as many macros as I want!
