Powder: Those boots pictured, the Burton Megaflex you mention, along with the similar late eighties boots from Alpina are all about twice the weight of the Sideral or TLT5, not really a good option for splitters at all. Certainly, someone could mod current lightweight AT boots with a sliding hinge like these old boots used, I even know of one TLT5 owner who is considering trying it as an experiment. Personally, I see no need to add the complexity and extra weight, the TLT5s can be made very flexible with some simple cuff mods, note also that a sliding hinge will interact with forward lean, this something to consider if you try it...

Now that I have had some time to look at the Sideral, it has a number of features I like; short BSL, easily modifiable lean, easy one lever lean lean/lock, and shorter medial cuff. Oh, and a neutral lower.
I too just finished rigging a pair of Sideral boots and have to say I am quite happy with the fit, flex and weight. I bored out the metal lock plate on the back of the boots- front foot as close to the screw as possible, back foot more conservatively to preserve some responsiveness. I cut down the medial cuff a quarter inch to promote medial flexion while riding and also grinded down the posterior "vertebrae" to allow the plastic spine underneath to move more freely. I have a high volume foot which is also flat/wide. I replaced the liners with Intuition Pro Tour liner and feel this to be a great substitute. Overall I have to say I have very closely mimicked the flex of my spark boots while gaining a boat load of benefits on the uphill. I am quite pleased with the cheaper price of these boots in comparison to the TLT5's. I found mine online for $250.00.
