I changed the needle in mine last week as I was embroidering on dog collar webbing which is quite thick. It was looping lots less with a size 14 sharp than the 11 that I normally would use in it. I would think it might depend on the fabric you mostly embroider on and maybe the thread you use also as metallics are known to work better with a bigger eye. Considering some people all use wing needles etc there must surely be some variation.
I like to use embroidery needles ( all sizes available) because they have slightly elongated/bigger eye for the emb thread.
Happy Stitching!

I always believe the manual first and besides, how much can a repairMAN know better than us and our machines? LOL, glad you are back up and running!
Sorry it was such a frustrating day for you and your machine. i guess we get to know our machines better than anyone.
got to agree with you every machine even if it is the same make and model will have its own little traits
