I have to admit to a certain degree of frustration over the actual weights of the discs I have acquired since I began (um, became addicted to) this sport. What is written by the manufacturer on the back is not always accurate, and based on my recent tests, more likely inaccurate.
I bought a digital gram scale that reads down to 1/10 of a gram and spent last night weighing every disk I own. To my surprise, most of the discs weighed either more or less than the number written on the back. I'm not just talking .1 or .5 of a gram, but several were 2 grams or more under or overweight.
One of the things I have been trying to do over the past six months is to cut down on the variety of discs I carry in my bag, decide on a specific discs to carry, and then carry multiples. As an example, I have always loved throwing a Champion Wraith. A 173g Champion Wraith was the first Wraith I ever purchased and boy, did I grow to love that disc. Well, after losing it in a pond, I purchased another and made sure it was 173g. Of course throwing it brand new was not the same as throwing my worn-in Wraith. In fact, it seemed like I was the one needing to make adjustments to accommodate the characteristics of the new Wraith. Eventually, after some wearing in, I again became comfortable throwing that disc. Since then, I have bought and thrown a half dozen Champion Wraiths, all with 173g written on them and I would say two of the Wraiths fly exactly the way I expect them to, but the others do not. A couple proved to be way too under stable compared to what I was used to, and others more over stable.
Over the past month, I have purchased three Champion Wraiths all with 173g written on the back. The idea was to carry all three in my bag in case I lost one, damaged one, etc. If I did so, I could just reach in my bag and pull out another trusted, go-to Wraith. Well, that was the theory anyway.
I did purchase the Wraiths from different sources - one off ebay, another from an online retailer and one from a local store. Not a one of them flies the same.
I weighed them last night on the scale, and despite all three having 173g written on them, not one of them weighs 173g. The weights are; 172.2, 173.6 and 175.5. Now, I'm not sure how much difference a gram here or there really makes, but I feel I need to attribute at least some of the inconsistency in their flight to the different weights?
So if I want three Wraiths that weigh exactly the same, is there anyway to really accomplish that, or will it always be a hit-and-miss situation?
