Using a 74 x 88 2blade on my Renesis.  I get about 6000 on takeoff= so=20 I would not say you have too much prop.   possibly too little if t= hat=20 6800 rpm is accurate.    1800 EGT is not unusual at peak EGT=20= & WOT.
 
.75 oz per gal oil mix.

I use the same mix, but at closer to 1 oz/gal.  Why?  That i= s=20 what Tracy does.  Dont think it is very critical over the short=20 term.  I have gone without oil for a tank or two when I didn't plan=20= well.  I have also put multi-weight aviation engine oil in (at .5 oz/= gal)=20 on one occasion when I forgot to bring along any 2-stroke oil at all.
