About to purchase my first set of new DR's in 15 years. REALLY like the sounds of the Digi-Troll 10's and the bottom track feature. Concerned about the negative feedback on transducer issues however with this feature. Those of you who use the Digi-Troll 10 with the bottom track, was it worth going this route or in hindsight would you have opted for a different model/make DR? Thank you!
