John.....here's another suggestion. Using guide charts are fine , but you have to understand these measurements are general. Here is what I do ,which may be a help in the future.

Using the general guide spacing provided by whatever chart you are using, tie your guides on with stretchy string (elastic string sold at most craft stores).
Once you have all the guides on and spaced per the chart, take it out back and cast it.

If it cast fine for you, leave it alone. If not change the spacing around a bit until it does (it is easy when the guides are tied on as explained above).

Not all rods cast the same even though they may be the same length. Once you have the guides solid on the rod and finished , it's a heck of a time to realize the rod doesnt cast very well. Using the stretchy string allows you to get the optimum spacing for what you need........just a little trick I've learned.
