New to looping..

[Tim Watson <timwatsontim@googlemail.com>]

Hi everyone,
Very glad to make your aquaintance, looper people.
I am new to this, and would very much like some advice before buying
my first piece of equipment.
I am a performing/recording percussionist playing many different
instruments, from djembe to congas to tam Talking drums to UDU clay
pot drums, and cajon. I also do grooves on the guitar, and am prone to
sing as well..anyway, the plan is to have a looping device to build
tracks for personal use...ie learning new rhythms etc, but also to
build loop tracks live.
I would very much like to be able to layer, say 10 tracks with
different instruments, an to also remove them one by one in a live
situation.
Questions
1. Would a Jamman be sufficient for this. Does it allow one to choose
which loop to delete, or would one have to undo the last loop first
2  You guys all seem very keen on Boomerang 3., but it doesn't seem to
allow one to load stuff onto the computer
3. Would the ideal combo be a Boomerang and a Jamman?!! This would
seem to cover all basses, although expensive to need both.

Any other ideas?

Thanks in advance, if anyone has the time to advise this newbe Looper 
person...
Happy days!
Timbo
