Purchasing the most advanced fishing line can be a sizeable investment. Utilizing backing line when re-spooling your baitcast reels can help make the most out of that purchase, saving anglers hard earned money in the process. Backing line is any line that is put on the reel as filler to have the primary line go over the top of it. As an example, say your reel holds 150yds of 12lb test. If you were to fill that reel with 150yds of fluorocarbon from a 200yd spool you would only be leaving 50yds on the spool, which is not enough line to go on another reel in most cases. Compare this with having 50 yds of backing on your spool already and you will only need 100yds of the fluorocarbon to fill the reel. This allows you to easily fill two reels from the one 200yd spool, thus creating maximum efficiency. Many anglers increase this efficiency by only removing 50yds to 80yds of the primary line from their reel when re-spooling and then only replacing that amount each time. These anglers leave a backing line on the reel at all times and only replace the last 50yds-100yds. Over the course of a season this allows them to use much less line and be more efficient with their line by utilizing the backing line. So what line could be used for the backing on your new reels? Often times anglers save old or inexpensive line to use as backing on reels, particularly when spooling new reels that they have purchased. Sunline has a solution to help anglers with their line management and backing. The new Sokomaki Backing Line is a simple solution to make sure you always have a cost effective backing that can be used on your baitcast reels. Sokomaki comes in a 1000yd bulk spool which allows an angler to fill numerous reels easily from one spool, preventing the need of keeping a large number of old line spools on hand to be used as backing. Sokomaki is made with a uniform and consistent 0.013 diameter, which is the equivalent of 16lb test. The consistent diameter allows it to lay on the reel in a uniform manner, allowing the line to be even on the spool for proper filling which enhances the casting distance and performance of your reel. Think of the line being a consistent diameter like stacking firewood. If all the pieces of wood are the same size it is easy to stack the pile quickly and efficiently, resulting in the pile coming out even on top. Similarly with a uniform line diameter the line lays evenly across the spool providing a solid and consistent foundation of backing for your reels. Sokomaki is a very cost effective way to fill new reels with backing for only approximately $0.01/yard. Utilizing backing when re-spooling your baitcast reels not only saves you money, but also increases the performance of your reels resulting in longer, smoother, and more accurate casts.
