I have used Cornilleau Hinotec Off-. Very flexible blade with decent control. The flared handle is excellent. The sweet spot is descent not large like MJ or ZJK SZLC. Pairs well with tensors like butterfly tenergy, donic acuda blue etc. All in all good for control with little compromise on speed.
Why not buy a Cornilleau blade, try it, and write a review? TT11.FR is most likely one company that has those blades, have you emailed them for an opionion?
