ESU Lokpilot in Marklin BR 53 (3301)
I'm planning to do my first upgrade.
I have a BR 53 (Marklin 3301) which was my first "real" loco after playing with Marklin Alpha as a kid. I always kept it in perfect condition and it has a special place in my collection. Nowadays it bothers me a little that it doesn't run as smooth as the modern locos and the lights behave analog even running it "digital" so I started to think about upgrading it. It has a DELTA decoder and the older motor.
I asked my dad who has a huge collection and he got me a "Marklin Digital 60760 High Efficiency Locomotive Motor & Decoder Conversion Set".
After lots of research I am wondering if it would be worth adding an ESU LokPilot decoder to further improve the characteristics.
Do you think it makes sense and which decoder would you choose? Is there a good website with information?
Thanks for your opinion and help.
