This question is somewhat misleading. Yes I know that line type, line diameter, amount of line on the spool and other factors can affect the depth a crank could hit but my question is a little more complicated than that.
I am trying to decide between two difference reels as to which will be my deep crank reel. One is a Lews Tournament MB 5.6:1 with a 23" IPT and the other is a Shimano Curado K 6.2:1 with a 26" IPT. To compare them I put 12# Big Game on both and filled the spools up completely and used a SK 6XD as the test plug.
While my comparison tests will probably continue I came across a weird deal which leads me to my question. They both cast roughly the same distance I think but I will say it seemed the line came off the Shimano better. During the retrieve the Shimano certainly felt more "solid" and smooth with the Lews more "geary" and sort of "looser." (I put oversized Winn knobs on the Lews and I REALLY wish I could figure out a way to put them on that Shimano!)
Here is my question. The Shimano was much smoother during retrieve and while the Lews felt more "geary" there was noticeably a lot more "resistance" during the retrieve which I felt like might be because it was diving deeper and that is what got me thinking about this. Again same rod, line and plug on both with the only difference being the reel itself. The Lews is a tad slower 23" IPT vs 26" IPT but I would not think a slower and possibly stronger retrieve would allow for more wobble or "digging" power to the bait to get down more. And while the Shimano was certainly smoother I would not think the reel would somehow limit the depth the bait could get down to but with the Lews there was certainly a lot more resistance, which I took to mean and feel like it was getting down deeper. Casting distance and the ability to achieve maximum depth are probably the 2 biggest factors here but I would really like to hear your guys' thoughts here.
