Back to the original question. I have also never played raptor so I don't have much of a feel for what bids show playing it.
But on the given hand I don't really object to any of
- Double, take-out of diamonds (with KQx KJx xx AQ10xx this would be clear)
- 1NT, though it's a bit light vul and would be my third choice
- 2C, for all the reasons mikeh mentions
I know you've told us what happened next, but I wouldn't pass.
To paraphrase the 'rule of second'
With a strong hand and shortage in their suit you should not be silent in second.
