The Saguaro is a very fast rolling tyre and it's not very grippy in turns. More side knobbles help if it's muddy but with roots and rocks the amount of rubber contacting the ground is going to help, low pressures will really help.
As to not washing out a Saguaro on the front, in fact not washing out any mountain bike tyre on 50% of all corners you ride, what the hell are you doing? Stop mincing, get your arse off the saddle, lay the bike over, feel the drift, deal with it, straighten up and peddle your arse off. Get you fingers away from those brakes, grip the handlebars tight and scream, lose the frickin anorack and rucksack and get really, absurdly, fit.
Blimey, I despair.
