So the critical consideration is how often LHO will have been dealt more than 10 red cards (you can't handle either 5-1 clubs or 4-0 spades with this line). A priori, 5-5 hands are dealt about 4% of the time, and 6-5's or 6-6's about 1.4%. So the ruffing squeeze line will work about 2/5.4 times, or about 37% of the time. This makes it upwards of a 20% favourite over the other option.
