I have two Super Rod Mega sets and all the pulling meshes, magnet chain set, swan neck, glider etc. Also got the Gecko....doesn't get used much BUT paid for itself on the job I specifically bought it for. Polymer set is also very handy. NONE of them are cheap BUT they have paid for themselves over and over again
overcoming access isssues does come a lot with experience and it is not really something that can be taught
