Okay cool,
if you play Axs bad oop on Ahigh (too aggressive and sticky) against IP-callers, right you have problems with domination. A9s-A6s are dominated by higher Ax and most of Ax-callrange MP-BU is better than A2s-A9s. I think all Axs are profitable to opens from all positions in 6max games. Most BU-Callranges are flawed, a lot of suited stuff which should fold or 3bet as default is a call for most of Microstakes players. We now dominate a lot of flushdraws and pairs (it is not about getting value by betting, we have better hands to realize equity by checking or check calling and checkraising).
A2s-A5s can get problems against good defenders in the BB. A5s for example makes a straight on 234 and Villain has 67s in his range (if we open the BU 2x he has 12 combos more of 67o).
Suited connectors are often dominated by better Flushdraws and straightdraws.
You are right in some situations suited connecors are highly profitable. If the table is to passive fold often and dont 3bet often, than you can raise them profitable, or fit or fold fish in the blinds. Against good players you'll get trouble because you have to fold against 3bets if you are oop all the time and good callranges crack suited connectors.
To prove the profit you furthermore need huge samplesize. You (turlock) are a hard grinder and I believe that you can prove the profitability of suited connectors in your games.
These hands are borderline, you are right, I am right, but borderline hands shouldn't be default openraises.
A8o CO: ugly against BU-calls, easy against 3bets, good equity against BB-callrange and good stealequity because cardremoval. A8o from CO is also borderline and mabye bad as default but A9o is much better, because combinatorics. There are much more 9x than 8x in BU-callrange but few enough to think about fold A9o.
Suited broadways are pretty obv opens from any position
