Enjoyed reading your report. Here are a couple of observations.
You didn’t mention refletching your own arrows. When you find an arrow you like, you are apt to shoot it a lot, and fletches do wear out. I would guess that I typically refletch an arrow 3-4 times before it is broken or lost.
You mentioned that you don’t tune your arrows yourself, but have watched the Black Widow video on tuning. I would encourage you to tune your own arrows. It is enjoyable and will result in a better flying arrow than you are likely to get from an arrow chart or calculator.
The exception to this would be if your shooting form is not very good. It is difficult to get a good result from arrow tuning if your shooting form is not consistent. But from your post, it seems you have a high level of interest in traditional archery, and certainly should devote the effort to develop good form, if you haven’t already done so.
Are there hunting opportunities where you are in India, and what activities are you doing with your bow?
