Two different bows will likely feel different to you. If it is enough to cause shooting issues, than you may have to decide which is better for you. "Mostly", if you are using the same form and the bow doesn't shoot where you are looking, than the arrows aren't properly tuned for that bow or you have gotten used to shooting improperly tuned arrows out of the original bow. I'm shure this is not always the case, but it happens frequently. Also, the sub concious is very powerfull and if it doesn't like something than there will be more issues.
The best way of choosing if you can't lay your hands on it, is to find something that resembles what you shoot well and try it.
A lot of people are too quick to give up on a new bow. If you give it 3 + weeks of resonable shooting time, It may fit as well or better, but if you constantly compare it back and forth ie. 10 arrows from this one and then 10 arrows from that one you will likely never get used to the new one.
JMHO-- I'm shure plenty will find fault with this.
