Most mod riders use Maxxis creepy crawler for there long lasting tread and good grip   The best setup and im sure other people will agree is a monty tyre on the rear and a try-all on the front.  People dont tend to get ear try-alls because of the soft compound they were realy quickly  Ive never tried the echo's so cant say much about them, so your best bet is getting a monty and a try-all   Hope i've helped   Ryan  p.s Where bouts in malvern you live? im down there every 4 weeks, you up for a ride sometime?
