STRINGS FOR A PEAVEY CIRRUS ?????

[mb94952]

I'm having a hard time finding strings that are long enough for my 4 string Peavey Cirrus bass. I love D'Addarrio's, but they are too short, even the XL's. I'm using DR's , on the suggestion of Ben at Zone Music in Cotati, CA, who plays a Cirrus 5 string. He's a cool guy. They sound great, but I want a wider array of choices.
Any suggestions from fellow Peavey Cirrus owner's ? Zone Music Rocks, by the way ! Thanks.
