I'd pass on Hughes, he finished the season playing for a team who were relegated to the bottom tier.
Monti is an interesting one, I watched him rip us a new one for Morton in the Alba cup a few years back and then score for fun for Pollok over his two season spell. When he finally got his big move he went to Dundee under Brown and didn't seem to do particularly well despite a promising pre-season- in saying that Brown is hardly a tactical genius and he impressed me when he came on against us in December. Wouldn't be averse to bringing him in, perhaps for a trial period first though.
