I concur with this suggestion -- the handle of any large mallet (Q-tip, yellow, or blue) should work. The Q-tip mallet handle made either the C2 or G1 sing quite nicely at the Area 10 conference this past June. On the aluminums, you may need to have someone else hold the bell while you stir, though. Above B3
may be doable by one ringer with long arms, but may get uncomfortable after a while.
