LoS blocking terrain in 40K?

[manrogue]

I was reading up on Caledonian and a lot of people mentioned that the games played were very tactical because of the amount of LoS terrain.

I can understand the need for this with the amount of ignore cover around now, so as a thought would it be worthwhile trying to introduce some at the club?

If so, what would be a good idea?

2 large pieces per board?

How tall? 20cm/8inches tall x 20cm/8inches wide/long or shorter/smaller?

Discussion and comments appreciated!

Edit - something like this mid table?
