SSWUP ISL - Your comments

[SSWUPinSA]

So I have bought my DCC system some time ago, a Digitrax Zephyr, seems to be all I need for this ISL and it is a breaze to use so far. Also have the programer so now all I need is to figure out the wiring.. I have PECO code 83 Electrofrog turnouts that I will be using so my questions are:

Is the Zephyr powerfull enough to run this layout without a booster?
Can I wire it as simply as Lance mindheim does the Palmeto spur in his latest book (Bus and feeders off to each spur?
Do I need to rewire the Electrofrogs as per the instruction in the package or is there another way or can I run them out the box?

Thanks

Callum
