The ART will have less initial lift than the HPS so I would bump it an inch forward . You'll also find at speed the ART will create more front foot pressure so going forward may not suit where you like your front foot to be . It's a chew and see scenario. This is where these titanium wing bolts come in handy . I use them on everything first up when I change things around . Super easy to adjust mast position out on the water without any tools .
