if you pick the best scrummagers then you will get more dominance and penalties
Ross got the top over the at the RWC, but didn't get any penalty tries, if you replace him with Adam Jones you would, also it's better to be not complacent in case they up their game, so I would play the best scrummagers first
just like how Leinster were dominant over the Cardiff Blues scrum, but the Ospreys dominance took it up a level
... and anyway Adam Jones has improved his ball carrying skills over the past couple of weeks anyway, when was the last time Dan Cole who people are putting forward due to his ball carrying did this? (The Hair Bear also did a lovely run and pass to set up a try against Treviso the previous week)
