Stiffness to weight the Extralite is a winner .. because it's so light! Seriously, if you're not aware Fairwheel bikes tested some stem recently which may be of some help? http://fairwheelbikes.com/c/forums/topic/2014-stem-review-3/

On the Kalloy I've not seen any numbers. But there is a large thread on Weight Weenies to have a look at with people recording weights etc. I'm obviously using one .. but I can't really give an opinion on its stiffness as I'm not the powerful a build

I did read that, it's exactly where I got my choices of Tune and 3T from. While the Stiffness to Weight on the Extralite is great, they also said it had one of the highest deflection scores. Admittedly, I'm only 63kg so snapping bars isn't exactly my problem, but being that floppy in testing doesn't exactly inspire confidence...

Those Kalloy's look decent, especially with some Ti bolts and a bit of acetone such as you've done! I'll pick one of those up, cheers!
