I like to think of myself as an expert on this niche subject as I wore my previous deep sea on rubber straps for nearly 7 years. Rubber B are imo the best. Tried the Everest but it just looks to narrow.
On the tang versus original clasp point, the ones that use the original clasp really taper down, I didn’t like the look. But it feels great with micro adjustment.
My preference was for tang on the rubber B. I ended up buying 8 of them to mix it up. I still have 5 and hope to get another deep sea to put back on them.
