The reason I asking you to migrate to grains as a measurement it is more precise, Think about it this way... on a larger glide bait that weighs 3-6 ounces.... 1 gram can make or break the weighting of the whole bait.
1 Gram is approx. 15.4 grains... Easier to be more precise.
My suggestion is use your paint and finish to get your weight to were you need it for the hardware you have, it will save you time, headaches and $$.
You will almost always run into a supplier running out of what you want....Happens to me quite a bit, have more than 1 supplier of the same blank if possible.
You also need to know that changing hooks and snap rings will change the action of the bait a bit.
