i have 2 - 15 year old chimera super pro medium strip banks. i love using them for rim lights and as main lights. i always wanted to get grids for them but they cost way too much from chimera. when i found out i could use the strobepro grids for it, i was estatic. the strobepro medium strip bank grids are 2 inches narrower and 1 inched shorter than my chimera strip bank. It is $80 to get 2 grids compared to get 2 chimera grids for $800. hands down i will go with the strobepro grids. i lose a little on the ends but it works great overall. so happy and saved a ton of money.
