"canbus" led's just have the load resistor built in. Unless you're reprogramming the bcm, you'll be using a load resistor on each blinker to avoid hyperflash. Your goal should be to use the highest resistance you can get away with to lessen the amount of heat produced. This isn't a "problem" with led bulbs. Hyperflash is programmed in your BCM and there's literally no reason for it to occur other than that's how chevy wanted to program their BCM to behave. It would be trivial for them to allow us to re-baseline the BCM to a different current draw but that's not how GM rolls.
if a bit of wiring isn't your thing, just go with the canbus bulbs. Worst case is you have a bulb fail at some point. If you're ok with simple wiring, then putting the load resistor away from the bulb is ideal. You can pick your resistance to fit your application and keep the waste heat away from the led and get away with smaller bulbs or perhaps bulbs with more led's or a different layout of led's than what you are stuck with on can-bus bulbs.
Either way, it should be install and never have to touch it again for well into 10 years. If your bulbs are failing and you're finding yourself getting different ones, something is wrong. Either you're buying crap components or you're buying stuff you shouldn't be.
