Hi Barbara,
     I have a hybrid D from 1981. No touchweight problems. The bulk  
of our B's, from 1965 or so (teflon I) are all teflon (other than the  
few I have replaced), and tend to have flange friction issues - and  
perhaps geometry in some cases - leading to touchweight problems (I  
investigate, see that the real answer is parts replacement, and put  
it off till later. No sense doing a bunch of work that I'll just redo  
or throw away later with new parts).
