Hi & very welcome Ghazz. Only thing which stopped me sticking with the Proraso Sensitive was the menthol kick (just cause I don't like menthol) ; otherwise I'd strongly recommend it.
I love Treet blades, in particular the Treet "Dura Sharp" and the red packet Treet "Double Edge".
These are carbon steel blade and hold a good edge, but do not last as long as stainless, but as they are much cheaper it does not matter.
There are some others I have not tried, but I presume you will be able to buy them in single packets so no loss if they do not suit.
