"Everything Matters" and when it comes down to custom building your own swimbaits or just adding a nail weight into your Senko to get that perfect ROF to trigger that strike would you believe water temps may have something to do with it? A bait that floats in the dead of winter may sink a little faster in the heat of the summer, that may make the difference!. At the bottom of the photo I will add ice and or heat to build my BBZ-1 swimbaits for certain times of year! Does it matter? For me it does.
