On the subject of what length needles are best

This might help you decide:

Skin Thickness and Needle Length

A 4mm needle length is proven effective for people of all sizes because...

 It is long enough to pass through the dermis into the fat layer,

 But short enough that it does not reach the muscle

Well to be honest, I always did use 6mm needles in the first place!  I tried 5mm and 4mm and it made no difference whatsoever, why would it?
 
Cannulas are 8mm, but I think that might be the introducer needle?  will have to measure one ....

The introducer needle you gave me to try just folded and didn't work at all Sedge, I'm sure in reality I will sort it.

Supposedly it doesn't matter. We inject into the skin, not into body fat or below it (hence why we don't heed a hypodermic needle in the first place!) and the layers of dermis that we have to get through should be about the same in everybody no matter how big the rest of you is. That's why hardly anybody uses the old 10mm or even 8mm needles anymore, in fact it turns out absorption is better if you don't go TOO deep, to say nothing of less pain!

That said, if you're worried that the needles you're using aren't doing the job for you, then you may well want to try out a few different lengths and see if you get better absorption out of them. Some people do find that the 6mm works better for than than the 4mm, for example.
