I got my first spinning rod with microguides back in 2020. It took me a while to get used to it. I've been using it for small moving baits, and fishing with a split shot rig. First off the microguides will pick up a ton of debris. If you're fishing in slop then you will have to clean off the guides about every other cast. I never noticed any change in sensitivity, but that may be the blank and not the guides. Forget about fishing them in cold weather, they collect ice as fast as they collect slop.
