Thanks guy"s!!! Well i will be honest, i have been out of the hobby for about ten years,never had time to spare when i was a teen,you know chasing girls,parties, cars,all that fun teenage stuff,but now that i"m an old married man in my early thirties i have seem to have plenty of time.I recently built a dragon sherman that i had for quite some time and the tracks were a little tricky and i heard about these metal tracks that you pin together and to me that seems a lot better than fitting with the out of the box tracks,plus people say the detail is much better.
