Merlin Agilis Geometry Questions

[amerikaner]

Hi All, hopefully folks with a Merlin Agilis can help. I'm trying to figure out the sizing on a M vs M/L...Seems like the 2002 and later Agilis' had the hourglass head tube, but the 2001 had a less dramatic shape. See pics below:





I found the 2002 catalog with geometry from retrobike, but is the earlier (pic on left) have the same geometry? I'm thinking no as the head tube is longer. Also, does Merlin use "Actual" or "Effective" top tube measurements?

The 2002 catalog lists:

virtual size = Virtual Seatpost??? or is this Effective TT???
frame size (c to c) = Seatpost
top tube length = Actual???

Anyone have the 2001 Catalog? or geometry?
