what i will say here is that you are getting A LOT of different suggestions on what people think are the best knives for them based on their own preferences as well as overall performance.
the first thing that you need to do is decide what kind of knife fits your needs and preferences first. if you like the profile of the konosuke and believe that you would like to replace/upgrade, there are tons of options out there (masamoto KS, suisin IH, etc). now, if you would like to get something to compliment your konosuke, then you would want to look into the thicker, heartier knives (heiji, gengetsu, etc)
i for one have a 270mm kono HD gyuto and a 210mm IH petty and complimented them with a 240mm a-type gyuto. i did this because i believe thick and heavy knives do affect performance no matter how thin behind the edge they are. if you like the laser and want something to compliment it but dont care for the thicker heavy knives there are also options (mizuno, a-type, etc.)
once you answer these questions, you will narrow down your search considerably. good luck!!
