I bought the trinity system. I really loved it. It makes it easier to tie loops. Although I wasn't happy with the legacy thread because it's so visible. Can you pls suggest an elastic thread that is more invisible than the legacy thread? Thanks!
Honestly I have only experimented with 2 or 3 different types but I found that I like Yigal Meskias ET overall. The ET isn't clear so you don't have to worry about light/sun reflecting off of it. The color is a dark brown/black so its easy to manage even outside on a sunny day. Hope this helps.
