That does help... I think i would prefer my cookware to respond quicker to heat and heat/cool faster. I have heard that the 5 ply was supposed to be better with not warping... But i haven't read anywhere about 3ply ever warping... So that advantage of the 5 ply may not even be a true advantage.

And when we say 5 ply holds heart longer... How much longer are we talking.

so i think I'm going to order the 13 piece set and sell the individual pieces that i already own in 5 ply

I found the d5 to be less responsive due to the extra layer of stainless steel in the middle of the aluminum layers in the center. The d5 may perform better on induction, but on gas I found the performance to be much worse (I basically ditched them). The Copper Core line is more responsive but more expensive. For better heat retention and more even heating performance, consider Demeyere.

Gooster is correct. The d5 was geared more towards induction users. I have both the older 3ply and a few d5 units. The d5 behave slightly better on induction. My Demeyere is fabulous on induction. I think the copper core is now being made for induction too. It would be interesting to try.

Good luck!

Ok.. I was looking at the 3ply... I've gotten really good deals on the 5ply all clad that i do have so that's why i got it... However after researching I've found that demeyere ranks and performs better than all clad.... So now I'm researching demeyere sets and individual pieces from them
