Just saying, this is what leads to CIEM's getting a bad reputation for being difficult.
You guys need to understand that the single most important thing is the quality of the ear impression and that comes down to whether you followed your manufacturers requirements exactly, and re-took your ear impressions if there was ANY doubt.
A one week wait to have the impressions taken again by a professional, or the social awkwardness of asking your audiologist to take your impressions AGAIN for the FIFTH time....is NOTHING compared to how you will feel when they come back to you in a months time, fitting and sounding like garbage. A great impression is KEY.
Thanks for the advice, i will keep that in mind.
