Yeah, I agree 8-12 openings can be made very effective if you work out good competitive gadgets (gadgets which should, among others, 'fix' the problem I mentioned). I'm convinced that, on isolation, 8-12 openings with gadgets are in the end superior to 11-15 or 12-20 openings. But, since you need to fit the 8-12 openers into a complete bidding system, that can force some changes.

So sorry, but I do not recognize you any authority to tell me how I should conduct my discussions. Now, I appreciate and thank you for your effort to provide us all with interesting information on weak opening systems (I knew most of it, actually). However, I won't comment on that info since it seems to bear no relevance for the original problem.

I see what you mean. One point: if you open 8-12, responder rates to have around 10 points. Therefore, he's likely face a competitive decision more often than systems that open 11-15 or 12-20, so precise gadgetry becomes more important.
