I do agree with you about currently how joining the LL would be no help for the likes of Talbot or other big Junior sides. But with a fully functioning pyramid with access to the lowland league and beyond, in 25 years time the Lowland league would be full of the best supported sides in non league football and a few league two sides as well. This would be a well supported league full of sides who have the support and finances required to play in a league with reasonable amounts of travelling .
It might not be great now but in 20-30 years time the lowland league has potential to be brilliant.
But below this every thing needs to be regionalised because it is a waste of everyone's times sending pub teams to play league games 100 miles away...
