If you are metal type chap - Ola has just done a Helix demo and has put his patches up for free.
Apparently Pete Thorn is going to release his Helix patches too.
I've got 2 main bass patches - my Cliff Burton inspired Mesa 400 rock / metal type, with clean options; and a GK based super-versatile patch with some switchable EQ curves, bit of drive and compression etc for just about everything else.
Then I've got a shitload of weird noise ones!
