If you like Montecs you should try VPA. They are a similar 1-piece design but use better steel, are tougher and easier to sharpen.
Really, it's hard to go wrong these days with so many good options out there. Others good choices include Slick Trick, Shuttle T, Wac'em, QAD Exodus, and Magnus Stingers & Snuffers. All will group with your field points as long as your bow is tuned and you have shooting good form.
