Just sand it down until you see glass and make em pretty, until they meet. Overlays, in my opinion, are for looks and to help round the edges to prevent the string from cutting or being cut. I don't see a need for a two inch overlay other than looks. The rule may be there to prohibit a person from touring on recurves as tip overlays. Anyway, you would be able to sand the tip from the bottom up towards the string groove until to meet the rules, however odd they are. Good luck at the shoot. I get half the trophy if you win though.
