If you had a chance to ride the original Kendas in the rainy weather you report, and had no issues with the handling, then I have to say: You could do a lot worse than the Kendas.
My P250 also had Kendas installed, OEM. The front tire I had to replace early, after a couple of repairs (plugs) due to punctures. The rear tire, I got about 14,000km wear out of it. So, they do last a good, long time. Of course, they aren't as grippy -- that's the trade-off.
