New brake pads....which ones ?

[Two dogs]

I am due new front pads on my S2R1000
I am running Braking STX front rotors .
I don't track the bike don't take a pillion or have the bike loaded with luggage.
Just normal road riding with the occasional spirited twisties and one tour a year.
I almost never ride in the wet .
The rotors are starting to get slightly grooved with the hint of a lip on the outside edge.
Should they be machined like you do to a car ?
I am after a bit more bite but don't want to shag the rotors .

What compound would the brainstrust recommend and reasons .
Sintered full or partial.
Organic
Ceramic

Thanks

I personally use EBC's sintered pads, braking distances even with the old OEM rotors was shortened and haven't had issues when riding in a more "spirited" way

So far you have three responses with three different answers.  Personal preference counts heavily.

If your discs are not stainless you do not want to use sintered metallic.

 A little grooving is not a big deal, the pads will conform to the disc and you end up with more surface area!
