I'd go with the aggressive, taller knobbies for the reason you pointed out. It's best to have as much confidence as possible. D606 front and a T63 rear. The rear tire can be found on Amazon for under $70 with free shipping, although you may need to buy two for this. The front costs around $90. The T63 is a directional tire and in my opinion hooks up in turns better than d606. I'm on my second t63 now. They just don't last quite as long as a d606.
