Another workstand question

[martint235]

The birthday fairy is going to bring me a workstand and I've narrowed my choice down to two:

http://www.ribblecycles.co.uk/sp/ro...-Workstand-T3000-Folding/TACXWORK200000000000

Anyone help with a preference. I'm not too fussed about folding away. My top tube I think is carbon, not sure about the rest of the bike but I think there's a fair bit of carbon involved.

Thanks
