Heard from the salesman of CP, both the ballheads been the same in load capacity, the only thing about 308 compared to 352 is the ease to do panning. Manybe someone else can enlighten us here.:dunno:
anyway...i had this problem when i bought my ballhead..tested both and find the the 308rc is much smoother...and more elegaant in design..load wise...i think its the same..
