Sam, the PA32 family contains a number of subtly different models, that all behave differently in the take-off phase. You might break them down at follows, based in their take-off performance;
1. PA32-300 - Cherokee 6, which will comfortably go out of the strips you're talking about, given the right conditions. Useful load circa 1,400lbs (although some late ones were certified at 1,600lbs)
2. PA32R-300 - Lance I, a straight tail lance, which is only just behind the C6 in terms of take-off performance. Useful load circa 1,250-1,300lbs
3. PA32R-301 - Saratoga, this needs more ground for the takeoff roll and the useful load is 1,300lbs MAXIMUM and often less (although very late Saratoga's with all the kit may have as little as 950lbs u/l)
4. PA32RT-300 - Lance II with the T-tail. Because of a lack of airflow from the prop over the elevator, you get no elevator authority until you approach take-off speed. This results in a 50% longer take off distance, over and above a C6, or Lance I, and probably 35-40% longer than a Saratoga.
You need to be absolutely certain that the other people speaking are remembering the right model, when they give you advice, as memory can be a funnily selective thing.
