sfek sfaika

could it be argued that changing a tzadi beis yosef to arizal or vice versa could be allowed because of the following tziruf: 1) ponim chadashos (sofek) and 2) kav moshuch (sofek)?

Carbon fibre pens

A trainee sofer in South Africa has asked me whether it would be permissible to write with carbon fibre pens that he makes. R. Ganzfried aside who permits barzel even though this is tantamount to engraving according to many, I have also seen the plastic nibs with the built in reservoirs.

I actually have no idea what a carbon fibre pen is. Would this be counted as similar plastic or would it be considered as engraving?
