Tachyon works very well with Donaghys AP (Armour Pruss) hitch cord (in a VT configuration) and used in conjunction with a Rope Guide. The outer sheath looks like it may be susceptible to wear if not used with cambium saver, rope guide etc. but these items are commonly used these days anyway. The colour is VERY visible in the crown but it is a new rope. This rope is also very light and packs down very small - the light weight will be a definite bonus when summer returns. It will be interesting to see how this rope handles ascenders in SRT access applications.
