Hi Rannick:D Good to hear, mate!
As I told you, I'm not an expert when it comes to different BL setups. But I can give you something to read about the Lehners:

I'm sure Mike, Serum and the others will give their opinions as well.
This is the right place to get some good advice and excellent service.
Another information you should provide is the number of cells you want to use.
I choose 14 on my Revoxx because I already had a couple packs, and they fit just perfect in my design.
