In reply to Tall Clare:
Phantoms are incredibly light and small, I bought half a dozen a year or two ago.
On reflection I wish I'd got all/ some Shadows though, as a bit bigger. The Phantoms can be too small to easily take a well wrapped-up long rigging sling, are a little too small to be easy to use with winter gloves on are IMO are limited to simple jobs like attaching a sling, rather than more space-taking rigging jobs.
