Yeah this is SOP to finalise who the third pacer should be before a test series.
Wonder who would you guys opt for.
Shaheen, Wasim Jr, and then any of Hasan/Khurram for the 3 pacers, with Faheem likely as 4th pacer and "allrounder" slot. Having said that, I don't know much about the non mainstream bowlers so just looked at their stats:
Khurram has 56 FC wickets at just under 27...not really setting the world alight there.
Amer Jamal 76 wickets at almost 33...he is meant to be an all rounder and I think I saw him play in the PSL? But with a lack of any serious pace and swing, I'm not sure what use he is here. Might be worth giving him a try above Faheem who knows.
