Here are a couple of short clips of me practicing with my Jim Jones Firefly.  Man I love this bow - nothing I have ever owned shoots like this baby.

I am glad it does shoot well because my mate put his mobile phone (camera) near the top of the drink bottle that I was trying to hit - at 28 metres.  It would have been an expensive exercise if I had missed -ha ha.

The second video clip is from the same distance -just wanted to check my form.

Oh yea - did I say I Love this bow.

Now that´s faith in a mate.  

Funny lookin' wood arrows you're shooting, Sutto!

I just got my FireFly from Jim a few weeks ago and I feel the same way, smooth, fast and quiet.
I had the pleasure of spending a few hours with him in his shop and he is a super nice guy who puts his customes first.

sweet bow, sutto - good shootin' mate!  what's the spex on yer firefly?

The specs on my bow are 43#@ 28" 62" long.  I draw 29 1/2 so it is about 47# at my draw.  Just a lovely light little bow that I can shoot all day long.  As you can see I am not built like Nathan Jones, so I don't need to be ripping my arms out struggling with heavy poundage.

The riser is Cocobolo and Zebra wood, bamboo cores with Tamo Ash veneers.

Overall, your form looks good. Nice line, good posture, solid bow arm. The thing that I notice in the second video is you are collapsing slightly before release. Watch your arrow on the first shot, it slowly creeps forward after you anchor. Last shot watch your draw arm elbow. It starts in good alignment at anchor and by release it has moved into a 5 o'clock position (if you're familiar with Terry's form clock).

The solution is simple. Once you're anchored focus on pushing the bow arm forward while pulling the string hand backwards. I like to focus on pulling my draw elbow backwards and feeling the scapula pinching together. While it is important to relax during the shot it is very important to maintain a constant pull.

As an added bonus, getting rid of the creep should also help rip the string out of your fingers during the release.

From the vids you posted that's the main thing I see. Like I said, overall very good. BTW, you have a great area to shoot.
