For a second there I thought maybe I could help you kiwi but, the glider kits you list are the ones I have. Flying sailplanes is one of my many hobbies.
I have seen balsa kits by Sterling of a Standard Cirrus and, a Schweitzer 2-32.
both have wingspans of about 1 meter.
BTW The Grob G-103 ACRO was the first glass ship I ever flew. I started in a 2-33, moved on to the 1-26, the ASK-21, and the Pilatus PC-11B4
