Ben, I have mentioned the Fuji Concept guide sizing and spacing before, ie, more guides and smaller. This does manage line far more effectively than fewer larger rings, whether this is from a fixed spool or a multiplier.
However, with lose line laying on the ground, the initial "funneling" of the line is perhaps not as critical.
Watching slow motion casts, it is very clear that as the line comes up from the ground and through the first stripper, it very often forms a curve that rubs along the blank until it is pulled under control as it hits the second ring. So, eliminating that loop would be my priority.
My suggestion is a bit unique, but what I would do is have your 16mm stripper in the normal position, your 10mm single leg in the normal postion, but between them, stick a12-14mm stripper. So effectively you have 3 rings where normally you would have two.
The principle I am working on is that the additional stripper will control the line as it rushed up, preventing the line from rubbing the blank. This is roughly what the Concept ringing is doing too, but in a slightly different way.
Tape the rings on first and see if it works
Having said that, I would have 2 x cradle strippers anyway rather than one.
