I own a '71 P-13 and a '83 Waterford Standard. I'll echo what [MENTION=38510]Scooper[/MENTION] posted above, even though the geometry on my P13 is a bit more aggressive then the geometry of his P15.

This past late summer and late fall I changed both Paramounts' wheelsets from 27" and 700c clinchers to 700c tubulars. The '71 wears Schalbe One (28mm) and the '83 wears Continental Sprinter Gatorskins (25mm). I did notice a very nice difference in the ride of both.

If it were me, and I could only have one, and it is possible to snag the '84 [MENTION=61614]verktyg[/MENTION] pictures above, I'd go in that direction. The '83-84s with that decal set are on the rare side. That one looks to be in excellent condition.
