ACS Pro17 Custom Earplugs

Does anyone use these earplugs? I currently have the custom Westone ER-15 plugs but think too much of the high end is attenuated, leaving me feeling detached and a bit of that 'underwater feeling' when I'm DJing. I've read the ACS Pro 17s have the flattest attenuation in this respect. Can anyone shed some light on their experiences.

For me, the 17 filters attenuated too much. Swapped it with the 9 filters but there was still too much attenuation for me. Other people swear by them though.
