jadi penasaran, akhirnya kepoin jg deh
semakin lebar blade, semakin lebar silaunya, semakin slow effort ngeretrievenya, semakin luas radius vibratetnya
semakin lama turunnya , semakin cekung bladenya, semakin besar gelembung udaranya
semakin kecil lebarnya kudu semakin cepet retrievenya
ini sedikit tambahannya
Colorado blades, being wider and sometimes deeper (you can get deep cup colorados), will initiate spinning at slower speeds and will spin at almost a right angle from the shaft, which is what gives them the "thump" factor. An Indiana blade is a bit narrower and will take a bit more to initiate spinning, and spins closer to the shaft. A french blade (Mepps, Blue Fox, etc.) is similar to the Indiana although usually not cupped as much. Dakota blades are basically an Indiana with the center cut out. Willowleaf blades (Roostertail style) require the most speed to keep rotating and spin very close to the shaft.
Now, to get to the issue of what type blade to use;
_1. If you are running the spinner by itself, the colorado will put off more vibrations and spin freely at slowest trolling speeds (.5mph ??) _
2. If you are running the spinner behind a dodger, use a stiff, short leader and an indiana blade (or dakota) if you want the spinner to track with the side-to-side action of the dodger. The centrifical force of the colorado blade will counter the dodger somewhat and reduce the side-to-side action.
3. Don’t use a willowleaf unless you plan to troll above 2mph.”
