I vote for the Sig Kougar, since I've built one. It builds easy and I fly mine with an OS 46 AX and most guys at my field call my plane a screamer, because she be movin and groovin. I was thinking of building another but with retracts. I would then go with a OS 55 AX since it will be heavier.
I also prefer the look of the Kougar. Here's the link to the Sig Kougar Build thread. My finished plane pic is on post #343. There are some progress pics during the build on earlier pages. I took my time building. It took me 8 months. I started in October and finished in May for our club contest. That was my whole intent for building. It will build alot faster. I did when first place for best in progress.
