Alex, it really is a case of you get what you pay for with crash helmets. Balaclavas are a good idea if you want your lining to last longer, the ones with exterior seams are the most comfortable.
I have composite lids from Sparco and Arai. The Arai was expensive but is very strong and light, the Sparco was a lot cheaper, is as light but has some flex in it so is not as strong.
That said, I use the Sparco for track days and save the Arai for racing.
I'm also going to Brands on the 6th, can bring both if you want to see for yourself
