Query on Rubber B VulChromatic for Rolex Submariner

Just like to tap some real life information from readers of Rubber B on their Rolex timepieces.

I am an Isofrane convert and generally likes nothing better than to fit Isofrane on my diver watches. However, I really like how the Rubber B fits nicely to cover the gap where the solid end links were. Plus the VulChromatic version has a nice strip of colour to match the Sub bezel, which was pretty cool by my book.

Question was... the Isofrane was relatively affordable at USD99 while the Rubber B costs between USD240 (solid colour) - USD280 (VulChromatic), so how do any current users found these Rubber B straps? Are they soft and comfortable on the wrist, and do they have the vanilla flavour too? If you have any pictures, would appreciate that too. I just don't want to spend USD280 to get the Rubber B strap, only to regret not opting for the Isofrane Nato Green later.

Thanks in advance!
