Hi laughableinsanity,
Thanks! Will post more when I can (it's a crazy period now).
Also, forgot to mention, those videos were taken when I first started out learning heel-toe too! I strongly encourage all to try. I have been playing tap-slide for almost 15 years and took about 4-5 years to get it accurate on all subdivisions and dynamic levels. Heel toe took only about 2-3 months!!
Most importantly, it sounds different too. So, even if u are entirely comfy with tap-slide's speed, learn heel-toe for a different sound texture. I learnt pretty much most of it out there...heel toe, tap-slide, side to side, heel down...And they all give me different sounds and feel...it's useful for more dynamic playing.
