This is just personal opinion so I could be way off here but I think Still will be much more open to the 'model' as he will be very familiar with the players we target, especially the french based ones. Mowbray liked his British based players and trusted them more than the signings from abroad, examples being Ekwah who he played consistently despite a poor start to his career here and he seemed to prefer Burstow over the other forwards. His signings throughout his career at Blackburn suggest he preferred signing players based in the UK also. Will Still however will obviously be more familiar to French based players so will be more open to having little power as he will know the targets anyway.
