15T Sprocket chain wear

As I am currently doing the SP2 swingarm into SP1 conversion I have been considering fitting a 15 - 41/42 sprocket combination, it currently has 16-42.
But I was wondering if anyone has had trouble with the chain excessively rubbing on the swingarm chain guard due to the smaller 15T sprocket?
After the work I have put into the swinger I don't want to risk damaging it.

I haven't experienced any appreciable wear on the chain slider using 15/41 final ratio.
Which is the ratio I've been using since I've had the bike.
The only reason I changed mine out was due to swingarm removal for engine swap with the race engine.
There was not enough wear to require replacement. It just seemed prudent while I had the swingarm was off and for repainting.
I kept the original "just in case" as it was perfectly usable.
If you wish to keep the 16T front sprocket, a ratio of 16/44 or 16/45 should equate close enough to the 15/41 or 15/42 ratio.
