I have not tried that method yet. I have read some threads dedicated to it and it sounds interesting; even more than a little intriguing. But looking at scales (and their reviews), as well as some of the comments made in the measure-by-weight threads, I have doubts/questions when it comes to the durability (lifespan), and accuracy (ability to hold calibration) of many of the scales. I keep seeing comments and/or reviews with phrases like "I'm on my 4th, 6th, or 10th scale" and "It worked great for the first month..."
I have no doubt weighing offers the best likelihood for consistency (I'm in my 50's and my eyes ain't what they used to be<which wasn't very good even then come to think of it> and it would be nice to stop squinting at the black lines against the black plunger of the syringe), and I like the thought of not having to clean syringes and needles. It also sounds like it may be faster (that squinting thing again). But I don't have a budget to be replacing a $50-$75 scale every year. $20 worth of syringes is a 5 year supply for me. I know a lot of DIYers are mixing just fine with $20-$25 scales; but that is where I am also seeing the most disappointments/failures. I am also of the school that you usually get what you pay for.
And last, I
do question realistic accuracy, verses potential accuracy. Syringes have the inherent potential for inaccuracy due to eyeball-error and increasingly larger graduations as you move up in syringe size. While scale
users have the inherent potential for inaccuracy due to using weight estimations (unless you are weighing each and every ingredient, every time you purchase it, and adjusting the g/mL weight of the calculator for that ingredient). Proponents of weighing say this is negligible and won't be noticed in the final flavor of the mix. And proponents of syringes say the same thing about its inaccuracies.
So,
for me, it really comes down to cost vs. convenience. And I just don't know. I haven't been able to bring myself to pull the trigger yet. But I certainly understand, and respect, those that choose to mix by weight.
Sorry, I didn't mean to hijack the thread, but you asked an honest question and I tried to give you an honest answer.
