Yeh, I plan to leave them like they are now.The springs on P3s are the most volatile aspects of a P3. Minor changes can make big differences. The wiggy spring is happier on your satin P3 than it is on your black P3. It really boils down to that. A new spring would be advised or at least stretch the current spring out just a tad. Or just leave well enough alone and be happy the swap worked.
Thanks.
