pretty much any PIAA bulb is going to be high quality, but I believe what you're suffering from is just the color of the bulb you favor. those blue/purple tinted bulbs (like the plasma, silverstar, ultra etc) are never going to be that impressive in bad weather.

In all the cars I've owned, I've gone through silverstars, hella's silverstar equivalent (i forgot what its called but tirerack sells them), piaa, raybrig, plug and play HID kits, OEM HID's, and probably more.

just in my current integra alone - its gone from
stock 9006 philips bulbs
9006 philips extended output
somewhere in the line up I got SI-VTEC foglights with yellow lenses.
plug and play HID with 6k bulbs
" " with 5k bulbs

and now currently on a HID retrofit with TSX projectors and philips 4300k D2S bulbs

since i work a graveyard shift, good lighting is very high on the importance list for me, so I've been through a lot of setups.

i was absolutely disgusted with the 6k HID bulbs. it was a marginal improvement over halogen, at best. when it would rain, i might as well have driven with the parking lights as my guides.

so I got the 5k HID bulbs, and it was HUGE improvement. however, i would still need to turn on the foglights just to be able to see the road better.

it goes without saying that the retrofit offers the best output and light distribution, the color of 4300k is perfect for me, and I dont even need the foglights anymore.

i dont think there is a Halogen bulb solution that will cure your situation, especially since you're already at the "top" of the list when it comes to bulb choice.
