In my opinion the blade is a fantastic kite and my personal kite of choice but when i was learning to use the buggy i just found it to much. At the time i had a 5m beamer 1 and a 6.6m blade 3. During this time i was learning basic tricks 180's, 360's etc and just found that the blade would lift me and throw me out of the buggy.
For this reason i always used the beamer, purely because it was so forgiving when i went wrong.
With regards to static flying in the right winds the sammy is a fantastic kite.
I am not sure what budget you are working on but i know for sure the sammy will be alot cheaper.
There is always the choice of buy the sammy, learn, then move up thats what I ended up doing.
