Well thanks for all the advice guys. And sorry for hijacking the thread but they always say to use the threads rather than starting another!
Finally decided to give a Merkur Progress a try, as it might be a bit more forgiving than the Bluebeards Revenge I bought to dip my toe into this particular rabbit hole. Will probably try it with the 7 o'clock and Shark blades first as I have a few left, then will try some others to see the difference they make.
Watched this guy on You Tube and he's quite informative. (I'm sure he should be cooking spaghetti sauce with Paulie!) Anyway he does some good reviews.
