Did you ever find a source for spline weights? You can contact Tom
MacNaughton (do a web search on his yacht design school) and buy some from
him. And from Elkhorn Composites, for $27.50 each, you can buy the
traditional ducks made from cast-lead:
Craig Smith or Dave Hopton

Westlawn used to sell white plastic, lead-free hollow, spline weights that
you'd buy then fill with BB's. I have these and like them well enough,
although I filled mine with lead shot from the local reloaders supply store
(gun store).
You can read Westlawn at westlawn RemoveThis @abycinc.org
I'm sure the Webb Institute and The Landing School can also point you to
sources for spline weights. From what I've seen, the spline weights range
from $20 to $30 or so (that's *each*, not for a set) and you'll want a
minimum of about 10. I have 15 and have on several occasions needed all of
them.
For your full-size lofting, note that a hardwood batten (1/4" by 1", as long
as your boat plus about 8 feet) works will. You can lay out plywood, put
nailers across the seams to hold them together, then draw in your baseline
and centerline, square off the stations etc. Put a fine finishing nail
through each offset point and instead of using weights, use spring-loaded
clamps to do the fairing with the batten. You sometimes have to mark a fair
curve, remove the batten and nails, then relocate some nails and re-bend a
fair curve with your batten a couple of times to achieve the fairest curve
that produces the best average through the original offsets (discounting the
outliers that are obvious typos that is.)
Here's a picture of me doing just that:
