The Guide is more of a Guidance shoe (slightly less posting than a typical Stability shoe), whereas the Omni has a bit of a wider, more stable base, and more posting. The fit is different between the two, but the cushion is about the same. Either way, you should be fine. I carry both, and have no problem hooking you up. You might even consider picking up a Neutral running shoe, as it will be more structured and cushioned than your Minimal shoes, but not quite to the extent that a Stability shoe is.
Saucony:
Stability - Omni, Hurricane
Guidance - Guide
Neutral - Ride, Triumph
Minimal - Kinvara, (soon to be) Hattori
Keep your eyes out for the Hattori, by the way! Our Saucony rep came in last week and showed us the pre-run of it... It's gonna be dope! 0mm drop from heel to toe, fair cushioning, velcro closure... 4.4oz!!! My only concern is the lack of rubber outsole, which means your cushion is grinding on the pavement with every step... Not sure how long these will last, but the Nike Free's and the Kinvara has been doing it with fair success.. Just hoping the cushion is firmer than the Kinvara, because those do burn out a little fast...
But yeah. 4.4oz, zero drop Saucony Minimal shoe... The Hattori. So dope.
