Hawk brake pads - worth it?

So I currently have the SSBC aluminum KH style replacement calipers on my car with their regular pads that come with the calipers. When brake torquing the car or holding it at the line while revving the engine, the car won't hold past 1,200-1,300 rpm. There is a line lock in the front brake line, same result.

I have read that the SSBC pads they give you are not so much and I am beginning to wonder about them myself. The car stops fine otherwise but it just wont hold before a launch. The brakes are all new and everything works as it should. They were bled properly and the rear brakes are adjusted correctly. The MC is sized correctly for the caliper pistons and the pedal ratio is also correct for the car. Yes, the calipers have small pistons but they should be able to hold the car a little better.

So considering everything is good and working and short of going to a 'better' caliper, the only thing left to ponder was the pads.

Was thinking about trying out a set of Hawk Performance pads to see if they would help hold the car a little better. Anyone use these pads with this type of setup? I've read good things about them but they are a little pricey at around $100/set.

Thanks for any input.
