Buy whatever you want, but don't try and tell me I can't tell TG to go pound sand with their s*** business practices. I will continue to support stand up companies that don't steal ideas and ship them directly overseas. Good luck with your build.
What has marlin developed for the 80? did he pioneer the low gears? or did mark's? did he pioneer the hi steer kit he sells? I'll give you the ecoseal, but i opted for oe. I'm sure Marlin is an upstanding vendor. And he produces quality stuff. The however doesn't mean others can't also do it and if at a lower price are crappy.
we all get different things from different vendors. spend your money as you wish.
