I think the first part, or at least my point about spinners in the UAE being comfortable to bowl long attritional spells, could equally have to do with those spinners having stronger FC credentials as much as the conditions being familiar.
The second point is more about cricketing acumen and experience - fully agree. The point about height was simply that all else equal, a taller bowler will at least have one more favourable variable in dead conditions.
UAE is one of the reasons for current state of PAK cricket - it has taken the core essence of PAK cricket .... and created a monster - Misbah ul Haq.
(@Slog - yes, they are not associate level YET, but in an universe of 10-12 Test playing nations they are now at 7/8 - that’s closer to associates than their contemporaries in Test world half of whom doesn’t even bother for this version and started playing Test cricket in last 3-4 decades - indeed an achievement which you may disagree but stop tagging me next time when PAK saves a Test courtesy to rain)
