Stainless steel, mylar or teflon? I have tried them all over the years and they all seemto achieve thesame end result for my sport engines. Maybe one typeis less likely togum shut than others? What type do you favour?
I'm going through my Cox engines and doing some rebuilding, checking rod slop, new gaskets and reeds etc., general fettling.

Would use Teflon or Mylar, Stainless can wear anodising of reed housing, or so
the experts tell me.
The Cox reedies are high maintenance, I much prefer the TD's all of mine
0.010, 0.020, and 0.049 are a joy to use and never let me down at the field.
Fettling is fun though, so enjoy. John

For the best overall, all around performance I would suggest the mylar ones. Some people prefer the stainless steel as well and they are a good reed, but go for the mylar over the lifetime of an engine.
