At NEAD and most RC tank clubs the 45 degree is not a big concern. At Danville where the level of competition is higher, this more relevant. I have never really used 45 degree defense and I have no trouble getting kills without it. It is just a matter of personal battle style. I just requires more movement to get a good angle of attack. The battlefield is very fluid and Veteran tankers are more aggressive and attempt breakthroughs. Less experienced tankers snipe and flank to get kills. It is all great fun and we team up veterans with the newbies to make sure they enjoy the battle and live as long as possible. That is why I always recommend a heavy tank for use at Danville is you are new to IR tanking. There is so much cover at Danville that you can always find a good spot to kill from. I can't wait to see you apple Jeff. Fins will prove to be an important feature lacking on many others aside from Impact & DBU apples.
