Haven't started a thread for a while! I'm getting a lot of mixed messages concerning Abenas and not just on this site, what I'm hearing a lot is that the Abena M4s have reverted to plastic-backing after temporarily being cloth-backed - now I may me asking here for proof of something's that's uncertain (and that could cause issue or unhelpful guessing) but 1. I really just want a clear with-evidence answer (if it's possible) and 2. If you can help me out it'd be great! So...are Abena M4's plastic-backed or not. In conclusion I once again must underline that I may be asking for an answer which isn't known - though I mean to insult nobody whatsoever!
