I once asked an Elite competitor why he had a 45" t/m, his reply was I only fish shallow. He wanted the head of the t/m as low as possible. I believe it should depend on your specific needs, personally I like the 52" but I'm a deep water guy. I have to admit in the spring and fall pulling the motor up has caused issues with some low skipping/side arm cast. But, the positives out weigh the negatives for me.
