How hard are the long rods to cut? I like using the stock on my TM7 extended out about 3-5". It seems like I could add some more notches to the ones already there & chop off a few inches or mod the top rod such that it could fold all the way, again cutting off a couple inches if needed. What sort of material are the rods made out of on the 2.0? I have a Dremmel & a hack saw & I'm not afraid to use them.
