With professional band, the slingshot can shoot very fast. What I focus more is the accuracy. I got a stick style steel balls catcher so that I can know where the steel more hit exactly.
When I shoot the arrow with slingshot, I use this small gadget got from Dankung.com. That really helps the accuracy very much. 
Just pondering on Sheshou bands after getting from you the Stardi 0.8 which is an Anti Cold band and despite that works well in the hot tropics. It is durable even after a few nicks and it didn’t tear easily. Thank Dankung

I'am very glad of my slingshot. It's a beautiful? collector's item and it is very accurate. Yank you for your couresy mail.
Best regards,

A breakthrough slingshot! The very comfortable grip and creative mechanism to fixing TTF band. I don't stick to 1 frame, as soon as I start to get familiar with a frame I get another and go with that until i get another..., so you can think me always being experimenting with new frame. This TTF model is by far the best TTF.
I can't say enough about the X6 Shining Edition. I love it in every way.
Before I say anything else, I need to clarify: Several reviewers have stated this X6 (Shining Edition) is 440 Stainless. It is not. It is 17-4ph stainless, which is a much higher grade. I believe the blue edition of the X6 is 440, as might be others, but not this one. It is highly magnetic 17-4ph stainless, mostly used in the aerospace industry, top quality.
This is a beautiful slingshot. I believe the colors are achieved by heat treatment, usually with a laser. I've had a couple of fork-hits, while I was snap shooting, and the color holds up famously. There's only the slightest discoloration. It's so smooth, so polished. One of the main things I like to do is fumble with it. It's truely an indistructable, life-time gadget. Such a thing is good for what ails you.
My favorite thing to do is flip shoot it, here's what I mean:
Hold the slingshot high on the forks. Start with it down in a resting position. Draw as you come up and barely take a sighting before you release. Don't really aim, just kind of quickly allign and point. Smooth and accurate, but also fast as you can.
You get really good at this quickly and it's just so fun. I think of it like a quick-draw.
Stand pretty close (10 meters) and use a pretty big target, like a paper plate size.
For this kind of fun, I get a slingshot without grooves, but to each his own. I see the X6 gives you a choice. Just start your pull staight up and the bands will alline fine. I never have a problem with that. Still, each must make his own way.
This is not only my favorite slingshot, it is one of my most prized possessions. I appreciate top quality wormanship, materials, and function. I want to take it with me when I die.
Just got this lizard king from Dankung's Davis, A workart and functional aiming slingshot!
