I'm looking at one that seems identical to the Loose gauge. Seems like its worth the cost to ensure all guy lines are tensioned up equally. http://www.zoro.com/locoloc-tension-gauge-70-to-800-lb-pt-1/i/G6231005/?gclid=CIP4pJaGy8oCFYQYHwoddiMEjg&gclsrc=aw.ds But its good for up to 800lbs. -- Bw_dw at fastmail.net
