Hello Rob, thanks for the kind offer to buy the blades from me.I said the same thing in my post that you have suggested in that it might have been a duff blade . There's also the chance that I could have been a bit heavy handed especially when trying out a new blade.
I'll try a fresh blade when I give them another go as I'm not ready to give up on them just yet.
Thanks again for the kind offer, it's very much appreciated
I'll tell you what, if the proline are not for me I'll post them to you free of charge.
