Get both!
What ever you pick, if you feel you chose wrong, pay the shipping back, and I'll build you the other. No hard feelings. I'm sure someone will be happy to buy that bow.
I will put you in the next build or current build and build you another the way you want it. I want my customers to be happy with their choices.
You might think this is a can of worms, but I spend time talking with everyone who orders a bow and try to figure out what suits them the best. I have only had 3 or maybe 4 come back and 2 were from the same guy.
Now maybe everyone is afraid... who knows.
I'm comfortable with the 58" at 32"s the 56" is certainly good to 30"s but you have to ask yourself what is the most important thing that you are looking for in a bow...not that you can't have it all, but as you start to creep twords the edge of the limits of one length, you might consider jumping to the next.
Now that last statement was for anyone who might read this post and not just TDhunter.
