Just some info regarding the BT-003 and the BT-003RS. They are 2 different tires. Very different in fact. The 003 is a straight race tire. It's not designed to work well in the wet, racers use rain tires for that. The 003RS is a "racing/street" tire. It's designed to work for people commuting on their bikes and going to trackdays. I actually ran/run the 003RS on my EX500(Ninja 500) track bike. I say used because I didn't race or do any trackdays this year due to the WR consuming my track budget. For the events and trackdays I did on the 003RS I was very impressed. No experience with rain though. They stick well until you start really pushing them to borderline expert club racing level. They slide predictably from what other have told me, I've never pushed them to that point.
WR250R - perhaps the ideal motorcycle for myself
Throw in a passenger and I'm unsure of what I'd consider ideal. Maybe a Multi?
I am now for sure sold on the Dual Sport style bike.
Keeping the Vulcan for now. The ladies seem to love it.
