old chain whip and removing 10 speed cassettes

[J Brown]

I'm contemplating going 10 speed on my new bike.

Can I use my old chain whip to remove 10-speed cassettes without
damaging them as the The Campagnolo Q&A so definitely warns against?

From http://preview.tinyurl.com/23es9y :

Can I use the old chain whip (sprocket removal tool) to remove the 10s
sprockets from the hub?

Absolutely not. The 10s cogs have a much narrower spacing and require a
dedicated tool with the ultranarrow 10s chain (UT-CS060). The old chain
whip would damage the sprockets because the chain is too wide.

There's other statements on this site that conflict with real-world info
from r.b.t, so I thought I'd check out this claim too.

Cheers,
