I've been told that an allen wrench connection running the long-lentgh of the trussrod is a bad way to adjust it; that a regular hex-wrench adjustable one would be better. What do you think?
Really? Hhhmm...I guess I should use your signature! I've only ever heard of using the T-bar hex's, though.
Shouldn't this be in "setup"! ? I'm not sure what everybody meant by these terms - I think that they are different in the UK. But I have used loads of different tools to adjust different truss rods and I can't see that it matters as long as it works!!
