If you can tune it to a good idle then go as aggressive as you'd like, just remember usually the more aggressive = higher rpm powerband and less mpg. You don't want a cam that doesn't have power until 3,000rpm when most of your driving is at 1,000-3,000rpm. Those cams you posted above should be good for power around 1,500-2,000 rpm and up I'd think.
That is exactly my thinking. I know that Hemifever could dial in any of these cams and make it idle. I just don't want to go with a cam that is going to be so big that I lose bottom end and gain a huge top end that I won't be able to get full use out of. Need to keep as much bottom end as possible to get my heavy truck going.
