Tires for 1980 Suzuki GS250T

Im ordering new tires for my vintage suzuki but dont know much about common practice or tread patterns. Plan on doing almost exclusively street driving, including in the rain.

Am leaning towards Duro HF308 in the rear and HF307 in the front. Im a little worried about their performance in cold rain/slush, any insight?

Any other recomnendations would be great to. Gonna be riding in the Oregon winter.
