Looking for experience with the Calcutta D for musky fishing. The youtube video is impressive. We have a couple Calcutta Bs, and a NACL. Thinking about adding the Calcutta D to the repertoire for it's reported smooth casting. What is the D best suited for? Cranks, twitches, gliders, medium sized bucktails? It looks like the gear ratios and line pickup numbers are different between the 300D and the 400D. Any noticeable difference between them? is there a power handle available? Can you burn double 8's and 10's without killing yourself?
