Mach sails have a higher upper end, but not a lower low end. If your Moto 7.8 isn't enough for low end, get a Moto 8.4 or a Mach 8.5/8.6
I myself don't have Motos, but have an Overdrive M4 7.8, an Overdrive M3 8.6 and a Mach 5 8.6. The Mach sails are just beasts - they pull you onto a plane and through lulls like a freight train.
Highly recommended if you are an experienced slalom sailer, but beware of the weight, the long boom needed, the center of effort far back.
Overdrives are a tad easier to sail/waterstart if you can still get one, need substantially less boom length and are just as fast for us hobby sailors.
