Have had two tail stalls in 15K hours, both in C421s when tail boot valves failed. The symptoms included pitch excursions and a 'buzz' through the yoke when the stall occurred. Not fun!!
Biggest thing is stay out of ice and , if you find yourself in it, get out. Icing here in the Great Lakes area is usually no more than 4,000' thick, though I have seen icing conditions 8-10K thick. Almost all piston aircraft, deiced or not, don't do well in icing. Turboprops have better climb performance which is great. If descending, increase descent within reason to minimize exposure duration.
