Hi Craig.. welcome to the straight path... it will lead you to territories of BBS cheeks and xyrophobic (just love to use that word) whiskers.

I haven't got a bad case of RAD yet so I only have 4 razors to compare with.. One is a wedge, two real hollows and one a bit less hollow I would say half hollow (it says extra hollow on the blade)..
to start with I would go for something hollow with a roundpoint. If you have a tough beard I would go for something less hollow..But I think it is all a bit of personal prefference.. but always make sure it is has been honed properly!!!
