I just took advantage of the sale and ordered the Flex 3401. I have a recently purchased GG6 that is still eligible for return (not purchased from AG). With the superior capabilities of the Flex, is there any good reason to keep the GG6? Is there anything that the GG6 is better at or SAFER FOR? I'm just a DIY guy, not a pro, so I don't see using either machine more than a handful of times a year. Thanks for any input!
