Planning a trip up to Etosha at the end of April.

Ive done a lot of travel through Nam but never got to Etosha. I decided to head straight to Etosha and spend the time in the reserve so I will use the trans khalari route to Gobabis.
Can anyone advise the condition of the C30 through Steinhausen, Hochfield, Otjosandu to Otjiwarango? from Gobabis
The main road heads to Windhoek and then north to Etosha, which looks like a really long way, The C30 is a shorter route, but is it quicker? or perhaps just more interesting.....
any advice will be greatly appriciated.
