welcome to srp.

Not sure where you got your razors from, but as long as they are honed properly you should be good. If not, perhaps your best option is to send them (at least one of them) to some of the members who offers honing services. Poona is in UK and does that iirc.

As far as proraso products, or any other shaving products for that matter, different people prefer different things. The most basic stuff is shaving soap or cream and a brush. There's preshave, postshave oils and lotions and a lot of other things, but a lot of it is just marketing gimmicks. I'd say the simpler the better, get a soap or cream and a brush and if you need it use whatever aftershave you've been using before.

if you ask them trumpers will probably send you a sample of their products. i very much like their skin food (usually used as aftershave, but some people like it as a preshave)
