Chest is so pumped by the end, it feels like its pumped the next day too. I am not a believer that fly/extension exercises for chest are only for isolating, I do think they play a role in adding thickness.
The best part about this is by the time I am doing pressing exercises my chest is very well warmed up and pre-fatigued hence I don use as much weight which gives me a piece of mind re-injury prevention. There's a video here where a fat perma bulker rips his pec doing 100kg.
