I have had the Nevegal DTC for a few months now and I can say, it is one of the versatile tires I have ridden. I recently switched from a much lower profile tire and the larger blocks dig into the loose dirt very nicely. Despite having such good dirt penetrating abilities, the Nevegals roll very well on hard-pack dirt due to its L3R (Low Rolling Resistance Rubber) and tightly spaced center knobs. When that dirt becomes sticky mud, it clears it out just fine but not as well as purpose built wet tires. The Stick-E compound provides amazing grip which provides confidence in the corners. It is actually the best cornering grip I have experienced but i have not yet ridden the Maxxis Minion 3c tire.
Despite being so versatile, the Nevegal does have its flaws. The tire weighs in at around 700 grams so while it isn't necessarily DH heavy, you could go lighter. Also, the sidewalls are very flexible which leads to tire roll. While it is necessary, to much is not a good thing. However, this only occurred while running the tire on my thinner rims at low air pressures. I then slapped them on my friends wider rims and put them at 45 psi and that excessive roll was gone.
All in all, the tire is extremely versatile and can be run at either end of the bike. The biggest flaw can easily be fixed and at 2.35 width, it holds its own weight wise. If you are looking for a versatile trail/ all-mountain tire, you would be hard pressed to find a better tire.
