[TowerTalk] hairpin matches

[r miles]

I recently acquired a 5 el HyGain 10m monobander on a 24' boom. The yagi 
uses a hairpin match. The plan is to convert it to 6m. Either a WVO 
special on 19' of boom or use the full 24'. Since it's already in place 
we are considering using the hairpin. Obvoiusly  shorter as the freq is 
nearly double 10m.  My friend W4HLR  will be actually doing the 
construction.
We would like to hear your experiences with HyGain hairpin matches on 
monobanders. Or any monobander.  Is there an advantage using a hairpin 
rather than gamma or other methods. DX-Eng sells hairpins & say they are 
better than gamma, etc.
We're hoping to end  up  with a heavy duty yagi as the boom & element 
sizes of this yagi are bigger & heavier than most  6m yagis.
It will be for  next seasons 6m Es. If there is one. Hi! Really was poor 
this Summer in NW Tn.
