That's going to put them at a disadvantage though. KERS will be much more efficient compared to the systems used last season (remember the KERS cars that had braking problems?).
Yes they will develop other areas more than other teams, but I think it'll be sacrificing a good opportunity.
With regards to the drivers, I too rather see 2 enthusiastic drivers trying to rampage up the field, but in terms of R&D and running of the team, it needs to have an experienced driver to help lead, otherwise there will be a lot of rivalry of who takes the number 1 spot in the team, which can lead to civil war.
