Thanks Carl,
I kan put on an anton bauwer battery and the MA-200 Shoulderlean/pad (shity english sorry) that adds about 1 - 1,5 Kg to the xl1s, do you think that will do?
I heard about the pendulum effect and about the 2,5 seconds by Erik and i must admit i havent even been there yet :-)
I am shure i want to take a class in the near future.
And most important i am willing to give it time;-)
Thanks again for the great advice !
