Yeah Im storing on my ledger but get confused between whether to store in legacy or segwit. I seen the other post regarding it and it recommended store in legacy, so will give that a whirl, cross fingers and hide until its done 
I was also wondering if the segwit address would be OK for the bitcoin gold, but now it's clear that the legacy address is needed for that. Thanks for the info, I have to move some dust from the segwit address to the legacy, every penny counts no probs bitart, if you get a chance look at this bitcointalk post about it:

Its confusing for me but the end result seems to be legacy is the way to go for ledger.
If anyone sees an official post from Ledger feel free to correct me, but thats all I have to go on so far.
The official ledger post regarding a split and your btc, is here. Its quite vague.
