Personally I wouldn't advise a 1700-rated player who wanted to improve to play these lines, but if you want to play them and play them with a good understanding of current theory, you definitely should get Avrukh's book. Nothing says you have to commit every last line to memory. You can treat the book as an educational resource according to your own methods, and I'm sure that having this excellent work on your shelf will contribute significantly to your understanding.
If this were true I should have the understanding of a GM by now!

My shelf is full of excellent and not-so-excellent chess books. My method in most cases is buy, browse occasionally, and don't remember much...
Seriously, I agree Avrukh's book can be used as low as 1700. For example:
- Play blitz games online and look up the theory afterwards, comparing with your own thoughts.
- Start by studying only the main lines (in bold) and read Avrukh's text comments; ignore sidelines until you have faced them in a game.
- If you want to memorize lines, set a limit at maybe move 12 or 15 and ignore lines beyond that point. Most of the Fianchetto KID and Grünfeld is calm and non-forcing enough that you can get away with this, certainly on 1700 level.
