SemiFlex filament on Printrbot simple metal

 I just wanted to start a thread to check if anyone has had experience using SemiFlex on a Printrbot simple metal ..

Basically there are a couple of  hacks to modify extrusion, something similar to the ones implemented to print NinjaFlex(https://www.youtube.com/watch?v=2EAOJjQMxFE)..Thanks

Also suggest a semiflex filament brand if you have had experience with any ..
