Puzzling bidding question

[Cyberyeti]

Most of the books and articles (example) I have seen on the idea either talk about exercising judgement or explicitly point out that the suits should be good, so I would regard your approach as mainstream. The question becomes where the cutoff lies - QJxxx and A9xxxx are not great suits but also not bad, so I could easily see this hand coming up on either side of the line for different pairs.

 

We're quite specific about it, it's an extension of playing 1♥-1♠-3♦ as 5-5 one of top 2, 3 of top 5, not a huge amount outside. We allow a little latitude when 6-5 but not this much.
