wolff calibration pac??

I recently added a slide mount rail and scope to my springfield 1911.  It was cycling .185 zero swc no problem.  After adding the rail and scope there are cycling issues.  It was expected.  However, does anyone have any thoughts on spring weight.  I would really rather not have to purchase the entire calibration pack.  $45 seems like a lot for, what ends up being at the end of the day, a single spring.

Buy 10-13# individual springs. That should do it for your various loads.

10, 11, or 12# springs

Thanks for the info!!
