I started out with a pair of 705's on my tiger, but swapped to K60 Scout rear and Karoo 3 on the front.
When my wife and I bought an NC700X, it had a pair of stock street tires. We swapped those for a pair of 705's.
The 705s are very grippy, and I find that due to their tread/macro-keying, gravel roads tended to be their threshold. I would softly wash out but re-catch the front while on a gravel campground road that had been filled with a bunch of rocks about the size of my thumb. Hopefully that paints a picture well for you. That said, I trust them to handle anything I will throw at them on the street, including hard leans. Given choppy, imperfect streets, gravel on streets, and the desire to ride hard on-road, and judiciously off-road, we picked them to put onto the NC700X. Its been probably 1200 miles since then, and I regret nothing with that.
The K60 Scouts are great all around. I watched FortNine's review of them, and think he is spot on. Plus with the mileage you can get out of them, I think they are competitive in cost effectiveness. Their large lug gaps (again, macro-keying) don't restrict you a whole lot in what you can traverse.
The Karoo 3's were picked for a similar reason, although fronts always last a long time. I wanted a large lug and valley tire that didn't compromise grip in leans, and the chevron'ed lug pattern helps to ensure that there is no moment that the contact patch fluctuates in support/grip. It is slightly buzzy on the front, but I'll take it if it means I don't wash out the front while braking hard offroad. What reviews say about the buzziness is misleading though; the buzziness is so miniscule, that I have completely forgotten about it--it tends to dampen out when >25mph.
Food for thought and I hope this helps
