The Kingpin will be the one you want for pin brightness of the 3 you mentioned, but if you are open to other options, you may want to look back into the newer CBE Tek sights (if you liked the features on your old one). The pins are much brighter on the newer(2016 or 2017) Teks. Now they are not as bright as the Kingpin, I'll be honest about that right off the bat, but they are very bright outside(with no halo effect), and look great inside while using the provided light. I had both a Kingpin and a newer Tek Hybrid Pro at the same time a few months ago, and now I have 2 Teks. Both are as solid of a sight as you will find on the market, but the area where the Tek really shined over the Kingpin for me, was the weight. The Tek is much lighter, and made a big difference for this guy who refuses to use a side/back bar on his hunting bows.
On another note......The MBG single pin might be a great option for you too. Not as many features, but super solid, BRIGHT pins, and not as heavy as the KP. Different strokes for different folks. Hope you find what you are looking for!!
