Well, there's no reason why my experience should translate, but here's a few observations:
If I were asked for a recommendation for a first razor, it would be a 5/8 full hollow round point, so the razor you've got gets the thumbs up from me. I've revised my opinion about this, because at first I started out with a quarter hollow and thought that full hollows would be skittish and temperamental, but experience suggests that the exact opposite is the case. Therefore, a razor with a stiffer grind will provide you with quite a change of feel. My Buddels are half hollow ground and have a nice weighty feel which encourages me to take my time and exercise a bit more care, so that's a possible course to take.
5/8 still seems to me to be close to the optimal width - for my rather angular face. Whilst I do enjoy using the big Hamburg Ring (13/16), it isn't very nippy in the concave areas, and it's far from ideal under the nose. 6/8 works all right though, which shows how much difference a sixteenth of an inch can make. I've had more success with narrower razors, down to 4/8, and consider them more versatile. I have a 3/8 out for honing at the moment and had an interesting (but lousy) shave with it before it went - it really did need some attention! That's a bit too thin for a second razor, probably, but a 4/8 or 9/16 would be manageable and they seem very good for getting those sideburns deadly accurate.
Finally, point styles. I really like square and French styles, but they are intimidating till you get used to them. Again, they encourage a bit of extra care (good) and allow pinpoint accuracy. So long as you're happy with manoeuvring a straight about your face I'd strongly recommend either of these styles for a change: they'll raise your game. These sharp pointed razors are much easier to get on with if the point is softened slightly during honing.
The short version: try an incremental change in width and a sharp point, and possibly a stiffer grind, but don't make a huge jump in any direction. Place of origin doesn't really have much of a bearing on the quality of a razor, so far as I have been able to ascertain. A lot of German companies used Sheffield steel anyway, and the forging and grinding is at least as important as the metallurgy, probably more so.
