Hi Adrian, I just moved my 12" Lightbridge optics over to the Geoptik.
I changed out the primary knobs to something smoother, also the washers are now Teflon. Painted the mirror tub matte black. And moved over all the accessories from the LB. Filter slide, sec dew heater, focuser,finder. I'm using the Geo spider, but with my LB sec holder & mirror.
Moved the handle over for left side viewing. Did you purchase the balance weight as an extra? I'll put up pictures, soon. I would love to see what other changes you make.
