But I get what you’re asking.
All 4a and 6a bands who want a real chance of state qualifying are thinking about it now most likely.
With the Region 4 addition of Cal Allen and Alice, it does add a new dimension since they will once again be involved in a state marching band year with their drop in classification and both of them no stranger to State.
South Texas by which you likely mean the valley based on the last time 4a region 4 was at state did take the 4 spots available and may do so again.
4a bands are a different animal with much more emphasis on music rather than the smoke and mirrors of props so that would be a focus for anyone in any region.
