If I have a six-card suit and I belong in that suit I would rather play the contract having not mentioned my second suit.  Of course in the bidding you do not yet know where you belong so you have to make some sort of compromise between helping partner choose the best strain and depriving the opponents of information.

There is more than strain to consider. Even if you end up playing in the first suit, bidding the second suit will aid in partner's evaluation. For example if you open 1♠ and then bid a second suit and partner has a 10 count with xxx of the second suit, he may make an accurate decision to go back to 2♠ rather than if you had simply rebid the spades that he might have raised to 3♠.

So if you belong in the second suit you certainly want to bid it, and if you belong in the first suit you may or may not want to bid the second suit. That creates a strong case for generally bidding the second suit, though I could understand an exception for the OP's hand based on suit quality.

2H, Rosenberg's rule.

2♦, transfer, rebidding spades over 2/3♥.
Oh, we don't transfer here, too bad.

2♠. Generally I would rebid the hearts with this shape, but this particular hand looks like it will belong in spades far more often than hearts. I don't want to hear partner bid 3D; even if he has 4 hearts, I may be able to dump heart losers if they aren't trumps; my black suits won't benefit from being able to ruff them in partner's hand. 2♠ limits the hand quickly. Yes, I may miss a nine or ten card heart fit bidding this way. But I don't think I'll miss many good games.

Good bridge authors recommend rebid of the 6-card major UNLESS the 4-card suit is hearts ("never" bypass hearts) and with better than minimum, rebid the 4-card suit.  [snip]

There are several good authors. Not all agree with you, some do.

If you can find a reference by a good bridge author who does not share the view I explained, share please.

Mike Lawrence, in his workbook on the 2 over 1 system recommends to rebid the sixcard ♠ and not the fourcard ♥.
He makes an exception when the heart suit has more HCP than the spade suit.

But Mike Lawrence is not a "good bridge author"; he is excellent.

As against this Marty Bergen teaches 6-4-6 as the order to bid these suits regardless of hand strength and whether the 4 carder is major or minor. Suit quality can still be taken into account: I doubt Marty would bid 2♥ with ♠AKQxxx ♥xxxx any more than Mike would bid 2♠ with ♠xxxxxx ♥AKQx. I could argue the case either way and the partnership being in agreement is probably more important than which method is chosen.
