Quite. I've been doing a bit of reading lately with a view to dragging my trad rack kicking & screaming from the 1980s into the 21st century, especially with regard something to replace my set of original forged Friends, some of whose lobes aren't quite as smoothly rounded as they once were.
In the course of researching this I got the general impression that a standard US rack is one set of wires and two sets of cams, whereas a standard UK trad rack is two sets of wires and one set of cams (and I personally wouldn't feel all that comfortable with only doubles of 1 to 4 wires)
The conclusion I reached btw was to order a set of Totem Cams, with a #5 Dragon to round out the top end & a #1 Mastercam to go slightly smaller at the low end (so la la la, I'm not listening to anything about how great the new Black Diamond small cams will be)
