Thanks for the comments guys.
About the Bars, I ran them at 800mm for a while and found that some trees on my local tracks became a little close now and then, (If anyone is familiar with the Beechworth area, in particular the "Woolshed" area there is one section in that area where the trees are about 830mm apart, tight fit.) So I decided to cut them down to 780mm, then I turned two 10mm extensions for when I feel like using 800's again, such as at open tracks.
The feel of them at 800mm is great, but obviously height, build and personal preference comes into it. But the great thing about them is that they can be cut down like I said, I think that honestly Gravity 800's feel better as 780mm. I like them more than sunline 750mm, and Boo Bars 780mm, I have felt a couple different flat bars, and am not a big fan to say the least. The Gravity's have in my opinion fantastic rise and sweep.
They are the best bars I've ever had, and I'm not going anywhere else in the future as far as bars go. They are defiantly keepers.
Edit: Got some new brakes on the 16th May - New Code Mags, Will update photos some time.
