Am probably going to upgrade my snap connection to VDSL next month when I can get a new router.

Anyway, with its larger upstream, will it clobber the downstream of an ADSL2+ connection running alongside it on the same leadin cable to the house? What about others in the same bundle of pairs?

Hard to say,

This is how bad VDSL is affected by crosstalk from ADSL2+ customers. Notice the low bit loading and SNR from tones upto 512?
I am just over 100 meters from the Cabinet and the affect is a lot more than i expected

What about the other way around, which is what I am more worried about with the VDSL trashing the ADSL thruput?

VDSL2 won't trash ADSL2+, it's purely the other way around.
