lol. Well a mix is usually good. The thing is though, if you just got done with a hard lifting day, there's no way in hell you have the gas to do a high intensity cardio day as a finisher to your weights session. None. The only way that happens is if you take about 4-8 hours off in between and do it as a second workout. It's better to go low intensity immediately following a weight session as your body is already in the process of mobilizing fatty acids in the blood.
If you're doing the high intensity stuff on another day, then yeah go for it!
