It depends on the definition of being selective.
If being selective means pruning moves at the root(moves that are good in 1 out
of 1000 cases) then being selective can be a problem in longer time control
because there are good moves that the program always prune when time is not
going to help you.

I know that one of the improvement in Rebel10 relative to Rebel9 was to do it
less selective because it could not see some combinations.
