What exactly are you looking for? I COMPLETELY get the ‘wanting a cheaper option’ thing; tires can be ridiculously expensive; especially if you ride a lot. However, you seem to be all over the map and just kind of ‘stabbing in the dark’ in your choices. The Stealth is for drag racing and rag racing only (it’s a SUCKY street tire!). The Verge is marketed as a ‘sport-touring’ tire. Neither of which is really comparable to the Pilot one you have on their now. The Pilot one is more of a full-on ‘track day’ type of tire. Shinko does a pretty good job with ‘all purpose’ tires but they really don’t have anything like the Pilot one. I’d say the closest they have is the ‘Apex’, which I still wouldn’t put in the same league as that Michelin, not by a long shot.
Have you considered the plain old, regular Michelin Pilot Power (not the 2CT, 3CT, ABCDEFG or anything); you know, the one that was all the rage 5 years ago? The prices on it are down into the bargain basement now (I’ve seen them for less than $120 for a 180/55 online). It’s still a phenomenal tire and MORE than enough for street riding. The 2CT’s really have no significant advantage for street riding as the ‘2CT’ (2 compound tire) means that it has softer rubber on the far edges for SERIOUS cornering (the type that should be reserved for track riding).
