I've always used the SRJL-17 it is their linear pads. Always felt solid to me and always same feel at all speeds and temperatures, I've always felt hesitant in getting the progressive ones due to unexpected results at random times. Have used EBC once before I learned about Vesrah and wouldn't ever go back. Had the EBC on my 2005 636 and they felt decent at lower speeds and in the city, but at the track would heat up and wouldn't work as well. Of course its possible I had the wrong pads for the job, so consider that.
