it comes down to handling for the rider
considering every thing.

and some times rolling resistance under high pedal loads as the wheel alignment goes in and out and one counter steers more to compensate.
Lots of work was done on the Aussie track bikes with this {Kilo riding is the extreme of this}
It is all about the balance of every thing, well sort of, because there is compromise in all designs and selections

I grew up racing and building with 531 and SL etc.
When Columbus's EL OS tubes arrived circa 1991
we were skeptics
but after riding them
every one I knew was converted.
The bikes felt better heeled over in pot holed corners
off the seat clobbering 53 x 14 for all your worth to go across gaps
Road shock felt just the same
the bikes felt nicer in all applications
The stays and forks were the same, it was just the TT and DT up by 1/8" diameter.


and when MAX arrived, on the track no big fellas complained
and the big lads loved the road bikes made from it {but the MAX fork is harsh unless you are 80 plus KG!}
Total pain to work with.

I have not made a frame with std tubes since 1994
