Well here's my two cents. There is no 13 foot Breakaway that i know of that will toss 1 to 3 OZ. The ones I know of will barely cast the 3 OZ for the low end. They need about 4 to start kicking in.

If you need to add some angle to the Penns you can put a very small shim wedge under the rear of the reel foot.

The guide space formulas from GS's link are nice but you still need to do some work. For example , the formula requires you to decide where to put the gathering guide relative to the reel seat and also requires you to choose which factor best matches your rod. The trouble I see for a big 13 foot heaver is that you'll start by locating the gathering guide further out than anything they would recommend and you will need a factor of 1.2 to 1.25 for a meaty rod like that.

Anyway , I'm thinking the whole idea is not going to work BobS. You'll get more distance from a lighter rod blank. For 1 to 3 OZ you could try an XRA 1204 or a Loomis 1266 (1-4) or a Allstar 1265 (3/4-3)
