It is all about the leg drive. No leg drive = no Jerk. A person WILL NOT be able to Jerk heavy without a decent dip and drive.
The wider grip doesn't actually make any real difference. Just look at all the lifters with their various width grips. Not one of them is really consistent or we'd all be doing it wide or narrow. Any length is fine as long as you can do it and your comfy with it. A few go uber wide like Dabaya, even less go really narrow and just outside shoulder width. Most are wider then shoulder width. Just find something that is good for you and go for it.
I do know that if when you dip your wrists are feeling the bar then your position is incorrect. The bar should be solely resting in such a way as your wrists are not feeling the weight what so ever.
Dabaya has also not lifted well over the past 3yrs or so...
If you can go uber wide with low elbows go for it. If your wrists feel the weight then your position is incorrect. Try front squating with your wrists holding the weight = no way you'll FS much weight.
