I'd shoot for a 400-450 in the first innings. The openers are doing their job so naturally the last 5/6 wickets will fall within 80-100 runs. 600 is wishful thinking.
If our bowlers finally get their acts together which they should as the KCA team is (even if it's Kenya A) no better than our Khulna or Barisal. Even if they bowl bad, KCA should fold around 200-250. Depending on the time remaining on hand, we can send them to bat (so they can give our bowlers another spankin) or get some of the 'Stand by' batsmen and the 'flops' a chance to bat in the second innings in place of Golla and Hannan.
