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.

I've been riding the Sideral and TLT5 for a half day each, recently. While the Sideral's forward lean adjustability is great, it was to stiff in medial direction for my taste. (without modding it)
In comparison the TLT5 was much softer medially and therefore much better to ride.
Still, after switching back to my softboots I rode 30-50% faster, more aggressive, had more fun, warmer feet and less feet pain. Will therefore unfortunately stick to softboots, no compromise on the down accepted.
(maybe, when buying TLT5s and modding them over many days, I might learn to enjoy them. Still, for the time being I will rather try Fitwells)
