Half Pitch or Full Pitch?

I'm pricing rubber tracks for my 92 Yanmar B3 and I was on the phone with Curtis at Prowler this morning and he told me that in their experience the full pitch tracks 320 x 106 x 39 hold up longer on the Yanmars than the half pitch tracks 320 x 52.5 x 78. He said this was specific for Yanmars and not necessarily true for other makes. He said the reason was that the Yanmars undercarriage rollers were sized in such a way that overstresses the half pitch tracks. He said thats also why the OEMs for my machine are full pitch. What do you guys think? Thanks
