I will be hopefully finishing the comparison of these two blocks one day. I am swamped with so much crap right now it is looking like prolly 2 weeks. After using them both with 1/2" barbs I would use the Innovatek in my personal system. The performance is pretty similar (although my testbed changed over the course of the comparison so I have to redo them both) but the Innovatek is much nicer to mount (esp with 1/2" silicone). I really dig the industrial German look of the holddown too; it just looks manly
