We play the following weak 2H or 2S opening bid as follows:
REPLY - Regarding your query this is what we (SABF) allow -
Where you promise both majors or both minors, any 5-4 is allowed.The Wilkosz convention (2D opening) is specifically verboten as it is a Brown Sticker or HUM convention. Here, neither the major nor the second suits are known initially!
So to answer your query, at vulnerable you are OK, but when you are non-vulnerable you must adapt your anchor major length to 5 please. The other suit can be 4, by the way. The 6-10 and 5-9 ranges you use are perfectly legit.

Just a quick question: Is it true that partner is not allowed to alert any call after 4NT? This never actually came up as an issue but one of our playing opposition partners said that this is so.-------------
REPLY - Yes, and this is internationally true. The World Bridge Federation (WBF) have decreed that the thought processes - when in a slam exploration auction above 4NT, if the opponents are not in the auction - should enjoy a peaceful run to their destination. With no interruptions whatsoever.
After 3 passes we will enter into what we now know as "the clarification period." It is during this period that any misinformations or non-alerts are explained in full, and also all slam bids above 4NT be explained. These bids should be explained without the opponents asking. In other words it is mandatory for the bidders to reveal all.
After everything is clarified, the lead is chosen and we then conclude the Auction Period.

REPLY - Refer to your law book (Jay did the TD course). Law 75C - This is a MISBID and not a MISEXPLANATION. It is not an infraction. Even if you became declarer (or dummy), there is no need to correct anything before the lead.
Have a good laugh - no offence.
