Good choice. Only thing is once the jag gets close(within an inch or 2) in size of the severum it may be bad news for the severum. I have a 12" jag and he would destroy ANYTHING I put in with him. I'm not saying your stoclist couldn't work but jags are violent IME. The plan you have now should give you time to tell whether it will work out before permanent damage is done. Good luck and make sure to update..
