with the bikes getting back to oldschool weights and below
does getting the bike balanced ie friont to rear matter  never rearly thought about it

Well i would say that with the centre of gravity more central the bike would feel more neutral.
Although seeing that the weight bias wouldnt amount to more than a couple of pounds, i doubt it would have much effect.

Light bikes can tend to feel a little unstable compared to heavy  as they respond to small rider inputs in steering/weight distribution.

Dan, my bike used to feel back heavy if I picked it up by the bars and seat. Just changed the seat from a shadow crow with shadow post to a hoffman pivotal post with shadow slimmer seat. Nearly a 1lb in weight difference. The bike feels more balanced now, but didnt notice any real difference on Saturday night, first time out with the new seat. Hoping it will help me with stalls and grinds as I normally seem to not lift the back high enough. The whole bike is now just under 25lb dont think I wont to go any less really.

not sure but there must be somehting to it because in Phil's SBC write up it tells about them making the front end out of lighter metal so the bike balanced on it's BB shell.

on the practical side i lightened the front of mine by half a kilo by changing the forks and until i got used to it could feel the front end lifting just carving the ramps.
