I had issues with dunlop back in the 90's, so I have mostly stayed away. When I switched I went with Metzler, and I loved them.
My 950 came with the bridgeston tires, and I just couldn't handle them. I believe mostly cause they where biasply tires, and I never had those on anything before. I looked around, and opted to get the avon cobra tires. They seemed to be the closest design to the Metzlers I used to run and where radial. I've liked them so far.
I never even considered any mich at the time, didn't even cross my mind they made motorcycle tires.
Good grip and long lasting don't really go together at all. Neither will be cheap upfront.
Just have to figure out, should you go with cheap tires that won't last long, that do what you need. Or get expensive tires that will last awhile. Guess this mainly depends on what the future looks like for you, and how many miles a year you put on them. No point in putting 25k mile tires on a bile that goes 2k a year, as the tires will expire and become hard and have to be replaced anyway. (But at this point likely won't matter too much to you how much you had payed for the tires back in the day)
