Any of the 3 tires you listed will work well, they are all high mileage tires so you probably will be giving up some traction.
I have C2's on my bike (second set) and I like them, however, I will contradict what others have posted and say that I find them poor in the rain.

 

When I bought the bike {2010 Dyna SG} a year ago it came with an ME 888 on the rear. Ended up getting 15,000+ miles out of it so replaced with another one. The front was a Scorcher which seemed OK but when it came time to replace the front I added another Metzler ME 888 to match the rear. The best price both times was from Eastern Performance Cycles - had them in 2 days with no tax or freight.

I don't ride all that hard or fast but the Metzler's give a smooth quiet ride, good handling and excellent mileage. Like my indy said "If it ain't broke why fix it?"

 

I'll be going with the Avon's for sure. This particular bike is my cone/competition bike. Traction matters.

 

Glad I could help. I'll never understand why they still use confusing alpha codes. But for this who don't know here is a good page you might want for cross reference purpose.

I'm going with American Elite's shortly, my stock tires are cupped pretty good at 15k.

 

As was said earlier, Avon recommends 38F/44R pressures versus the Harley OEM recommendations of 36/36.

 

I ordered my Avon's from J&P, they were under $100 per tire. There is also currently a $50 rebate on Avon's if you buy front and rear, but the rebate offer expires in 2 days. After the rebate I'm paying about $140.00 for 2 new tires. Can't beat that!
