You don't see an issue with your neck?
Hello mark.
This is 130 kgs dead lift... A month into ss.
Is my back bending to extreme, must it always be straight as a plank? Or this is considered fine, and I can keep moving on.

Have you read the book?
My neck hurts after watching that vid.
Keep it straight.
Your back is rounding more than it should as you pull. At the top, you overextend your lumbar spine. You probably don't need to have people beating on your back prior to a 130 kg set of deadlifts. Save that for when you are pulling 300 kg. I recommend eating more, too.
You can order the book from the Aasgaard Co and they will ship it to you wherever you are. You can also probably buy the Kindle edition of Starting Strength. No shipping charges on an ebook.
