Reply to Custom Earplugs w/ use under HD-25

Hey everyone. I understand the custom earplug topic has been beaten to death and I've done my fair share of searching before posting, however I'm looking for feedback on which custom earplugs are best with my HD-25's? Obviously the HD-25's are "on ear" headphones so comfort may vary when compared to other cans. Appreciate your feedback on this as well as on the 3 earplugs in general.

I've narrowed it down to 3

Etymotic Musicians Earplugs
Westone Model 49
Sensaphonic
