You’ll also begin to see the sizes that go with those strippers.
Size 16 always takes the 8H and 5.5M.
Size 20 always takes the 10H and 5.5M
Size 25 always takes the 12H and 5.5M.
Remember this by simply using a second reducer at half the size of the stripper...16-8, 20-10, 25-12(almost).
Finally, as you use the KR Concept GPS for a while (NEVER USE GPS AND KR CONCEPT GPS TOGETHER AND ”COMPARE” RESULTS. THEY ARE NOT COMPARABLE) you will begin to notice that the range of stripper distances is relatively small for ”average ” rods - almost always between 18 and 24 inches. Soon you’ll figure out that the 16 stripper will work great at 18 inches, the 20 stripper at 19 inches and the 25 at 20-21 inches (from the tip of the spool axle). Yes, that is counterintuitive but remember, the reel is getting smaller (and lower) with smaller and lower reduction trains so it usually works this way.
You’ll also begin to notice after a while that the choke guide, in many cases, is roughly the same distance from the stripper as the stripper is from the tip of the spool axle. 19 inches axle to stripper - 19 more inches stripper to choke guide, and so on (priceless tip here).
So you see, with just a few ideas committed to memory you can know instantly the starting place to build a KR Concept rod for a guy using a 3000 series reel and 15lb braid (no matter the power, action or length of the blank).
Now you can worry about thread colors...
