On the rated circuit the Charles Owen is King in the Hunter and Eq Rings. GPA's were super popular and you see a ton of the Speed Airs in the Jumper ring. You still see plenty GPA's in the H/Eq rings but I feel like for every 1 GPA I see there are 5 COs.
The IRH is a little tight on my head - but not bad ... I have a round head so maybe I need to go try some helmets on at Western Saddlery or Christiansen's.
I wanted a GPA but is they are phasing out id rather not spend that much.
I have both the Tipperary and an IRH. I really like the IRH, but can't tolerate the lack of venting in the summer...in my opinion, it gets really hot/uncomfortable.
Hence I purchased the Tipperary for schooling in the warmer weather as it is heavily vented (i admit it looks a little strange, but the venting is nice).
If I were to show, I'd reach for the IRH.....the Tipperary isn't something that would look correct in a Hunter/Eq. class. JMO.
