valve leak (is this normal?)

[carp]

I already have the ipz hr5, i set mine up as a direct drive :

here is a video 2x16mm on boom 20mm on stick and 16mm on bucket using 4mm hoses http://www.youtube.com/watch?v=ztxGq...ature=youtu.be it was fast enough with the cylinder i had on in the vid but now i put bigger ones on its a bit sluggish, not really slow just not fast enough for me
