If I'm printing something that is going behind glass, I won't use glossy RC but I will use air dried glossy FB. Glossy RC is too prone to "hot spots" for my liking.
I love the current Jessop RC in the lustre finish. However, I have tried not to become too attached to "rebadged" papers, as there seems to be more scope for unannounced product changes. I have heard it conjectured that Jessop's is rebadging a major brand product, but only they know for sure, and (I guess) the situation may change at any time.
