Ear Plugs

I am thinking about getting some custom fitted earplugs made for me. I am currently using these:



Alpine MusicSafe Pro | Hearing Protectors for Musicians



They are very comfortable and they do attenuate well but I am thinking custom plugs will be better as they will be made for my ears. I am using the silver filters



These are the ones I will be getting if I decided to go a head:



ultimate ear | Ear Plugs | Hearing and Ear Protection London UK | Musicians Plug



Has any one had experience using the custom made plugs vs high quality generic ones?



Thanks
