Prangnell Rapkin Crown Albums - Quality?

I'm looking into buying one and have singled out this particular album because I like the way it looks.




They come with 'cream leaves'. Never having held one, I've no idea how substantial these pages are. I'll need to mount a few reasonably large blocks using large Hawid-style mountings. So my question is, does anyone know what sort of quality these leaves are?

If they are flimsy, I could just get an empty binder and find alternative leaves.

The Prangnell Rapkin albums I have are good quality - I'd say better than the comparable SG, at least in today's form. As they were second-hand, mine had older, thinner leaves, but I imagine most leaves now will be geared to take mounts. I usually buy quadrille leaves in bulk from here
