Absolutely. Do anything Jim T. tells you. He has guided me through many 1/2A building quirks and tips. Like he said, always start nose heavy and work your way back to the amount of twitchiness you want. A Norvel Big Mig is one hell of an engine. After they're broken in, some of them can turn certain props close to 30k. So if that's what you use, I would recommend a 7-10 ounce plane on 40-45' lines. The Brodak Baby Flite Streak is a great match for a Big Mig or a Tee Dee .049/.051, and is my favorite plane, I have one with each of the aforementioned engines. And you may find a simple pressure bladder is the easiest cranking, non hiccupping fuel supply to use. Those are quite simple to make in the shop and swap out in the field if necessary.
!/2A is pure unbridled fun. A well built one will go anywhere you point it as quickly as you want it to. It takes practice to learn to keep up with it, and also to build it so that it has good flight behavior. But they are light enough to punish and keep flying, especially if you keep some CA glue in your flight box.
With a Big Mig .061, you have enough power with the muffler to tame it with a prop to whatever level you can handle. If you want to squeeze into a 35' circle, you can use an APC 6x2. If you want to go out to 45', a master airscrew 5.5x3 will bust out some hot laps. An MA 6x3 is about the maximum, and you'll hear the engine getting a little unhappy in tight loops. An MA 5.75x3 id a good compromise.
If you use a Tee Dee, I'd say the same APC 6x2 for 35', an MA 5.5x3 for 40' and an MA 5.25 or 5x3 for 45'. These have been my successful setups with my two Baby Streaks. My Norvel .061 streak weighs 7.2oz, and my Tee Dee Streak weighs 9 ounces. With Master Airscrew props you'll need to buy the GF series 6x3 and trim it to your preferred size, and balance it.

Good luck and have lots of fun.
