Thanks everybody!

This is how Chinese catalog looks like:


And after 30+ mails to different "number 1 Chinese rubber track manufacturers" I finally got something that roughly represents a drawing. Its a screen shot, 200x200 pix. I modelled 100a and 100b to get better idea how this tracks look like and how would they fit my build. 100b came out as shown in catalog, weight is roughly the same. Guide fins are 15mm tall, outside profile is 12mm tall. This one is my favorite at the moment.

How ever 100a looks a lot different then on the catalog. In catalog inside guide fins look very tall, but on drawing they are only 9.5mm tall and outside profile is 15 mm tall. Weight is also almost identical to 100b (even taking in account that 100a in catalog is longer).

Any suggestions what to improve? (negative comments are also welcome as long as they are not trolling)
