I normally quite like dropping vowels and letters, but only when it creates a fresh, short brandable name. For example - Flickr, Grindr, Tumblr etc all benefit from the dropped vowel. Visually and phonetically they look and sound good and it gives them a unique identity. Also easy to remember despite the spelling alteration.
In the domains you've provided it doesn't really work. I think they're quite confusing actually. Too long, more keyword based than brandable and overall hard to remember.
I see these as reg fee value.
