wolff mini non-captive guide rod set any good? help for idpa or recoil.....

[plumbum]

i was looking at brownells and noticed this. its made by wolff.looks like really good quality.you can get factory spring at 17lb. or 19lb or 21lb.

the only thing is it would be nice to be able to get all the springs with the set. if im reading it right you can only get one spring weight with the guide rod...

any suggetions on what to get.? just go with the extra power spring 19 or 21...
