Yea I thought about a set but the sets are nearing my budget (and don't seem worth it). It comes with a glove and I do have a Japanese thumb draw glove, yugake, but probably wont be the same. I am also not sure if I should use a thumb ring. Plus the arrows included aren't or don't look feathered either. I might have to get everything separate sadly.
The Nomad set over at Freddie's site is just 277 USD and comes with arrows that have the synthetic fletching which is standard for Korean carbon arrows. They are fine to use.
No, do not use the yugake. Yes, do use a thumbring. If you need to use a beginners glove that is typically sold with Korean bow sets in the beginning, that's totally fine.
Yea I looked around more and it was pretty expensive.
Price should not be your number one deterrent here. Rather, its what I said. You'll have to gain mastery of the thumb draw firstly if you are ever to use a tonga.
Besides, you can actually somewhat easily make a tonga yourself by just harvesting a good piece of bamboo and cutting it to the specifications known for this device. As I have said before to someone here, consult Saracen Archery book for the specs on the tonga. I successfully made one doing just that and you can too if you just google search for the text and download it.
