Good mix and combo here; you've got some all-premiums, double letters, pronounceables, CVCV's, VCVC, YCVC, etc.
I'd agree with mwzd that .net's (this is in general, really, not just with LLLL's) are about 10% of .com's, but hey, like single-word dictionary domains, 10% of happybirthday.com can't be bad at all.
So this one is a very good mix and if you were to choose to have names in .net, short of the lesser-quantity but ultra premium combinations, this set is the kind that you would like to have.
At the present valuations this lot can easily go from the low $XXX (at an average of $10+ per, although some of these are obviously worth more) to the mids. But it'd be a good idea to revisit this in several months' time as it is sure to have well since appreciated by then.
