KZ400 Tire Recommendations? and Shinko 712 2K Mile Review

Hey folks! I checked the forums and didn't quite find what I was looking for, so here goes:
A while back I swapped the dry- rotted tires that came with my '78 KZ400B (they're gone now and I don't actually remember what they were off the top of my head) for Shinko 712s. It was the first tire change I've ever done, so I had some friends help and we got both tires + tubes replaced (after a few problems with slow leaks and pinched tubes). 

Long story short, I'm not the biggest fans of the 712s. Rain performance is not good compared to the old tires, even as worn as they were, and there are a lot of rough/ gravel surfaces where I tend to ride that the new tires feel super squirrely on. They're great in turns and high speeds, I've gotten really comfortable learning them over, and as long as the road is perfect they're fine tires, but it's too often I have to second guess myself on tight or poorly maintained country roads. Granted, I've only been riding for a year and some change now, so maybe it's an issue of rider skill, but I tended not to have these problems with the old tires. I used to ride gravel on those tires... I felt pretty confident in my ability to get around on a variety of surface conditions.

I'm wondering who all has tire recommendations from their own experience? I'd love to split the difference between the super round profile of the Shinkos and the super blocky profile of the old tires. I'm looking at Michelin Road Classics but have had some trouble finding thorough reviews as of late. The original reason I chose the 712s was mainly budget, but thankfully this time around I don't have that restriction as much.
