The Premium Colorado is a flatter blade than the Colorado. Its specific use is for water moving at 3.0 m.p.h. and faster. In the later 1990's we also found that these blades work exceptionally well in front of slower moving baits. Put about 6 or 8 4mm or 5mm beads on your leader and then add the blade with a changeable or folded clevis. This blade trolled in front of your bait at .8-1.2m.p.h. will rotate at about 30-40 revolutions per minute. The result is that you still have the flash and presence of of spinner blade without the turbulence that would disturb the roll of the bait.
