I like heavy tops for fixed tip play (my HPs with caps are 100+ grams) but not so much for bearing play. So I would want the aluminum one if the tip can be fixed.
Actually, these will not be the first Chico brand spinning tops. The old Royal Chico company from NY sold several tops in the 50s and 60s, including the Trom.Po, Astrotop and Chiquito.
