I would recommend using 1x1mm crimps for the 0.012 and 0.014 Accu-Flex beading wire. I would recommend using 2x2mm for the 0.019 Accu-Flex and 3x3mm for the 0.024 Accu-Flex.
The 3x2mm is a longer crimp with the diameter being the same as the 2x2--choosing the 3x2mm would be a design choice rather than a functionality decision.
