I wanted to vote for two of your choices but I am flying a Seagull Decath so naturally I picked that one, I wouldn't mind a Tigermoth very nice lookin plane. The decathlon is a nice flyer I started flying mine maybe a month ago and flown it alot even flew it tonight. I started with a Supertiger 45 with a pitts style muffler and then just a couple weeks ago I baught a used OS 70 FS and tonight was the first flight with the new engine. The ST45 was pretty decent for pulling it around I don't do extreme arobatics I just do the normal stuff I wont change my style since I put a four stroke but the extra power is very nice. I also don't use a Gyro for anything if you read the thread about the Seagull Decathlon there are a bunch of people who are relying on the gyro to get them straight down the runway but I personally don't need it.

Anyways I am sure there all very nice planes but there is something about a highwing plane like the decathlon.
