PTS Masada AEG Hop up

[LostThePlot]

I’m looking to upgrade the hop up on my Masada AEG. So far I’ve gathered that there are two main options for replacing the hop up chamber. Either the Wii Tech hop up, or SHS one. 
 

Does anyone have any experience with these two hop units? What are the pros and cons of each. 
 

I am also looking to put a HPA engine in it in the future, so would these be compatible with common HPA engines?

Cheers!

I have the SHS hop in mine; it performs really well.  I think I have a Wii Tech one somewhere as I bought both of them.

Have you used the Wii Tech hop up? I’ve read that the SHS hop up is decent but I can’t find much regarding the Wii tech

I haven't used the Wii Tech one as the SHS one does an excellent job.
