Just go to a tack store and try some on. To be honest, I don't think that there is a huge difference besides how they feel on your head. I mean some breathe better, or a lighter but they should all be up to the same safety standards.
I bought mine on sale for $50, it's pretty good. It's the same one I get everytime.
I live in Texas too and I ride with an Ovation Delux Schooler. Paid right at $50 from Stateline. To me its no different than wearing a ball cap in the heat. When I first got it, it seemed ever so slightly tight but with wear, it took shape to my head and now I don't even think about it anymore.
I'll be another vote for the Ovation schooling helmet. I got mine about three years ago when I got to the barn one day and saw a crack in the visor of my Troxel. This was before the Ovation schooler became really popular, so when I went to the only local tack store in the area I was disappointed to only find super expensime ($200+) helmets, until I found that one hidden at the back of the pile. Bought it, and love it! It looks nice, is low profile, and fairly cool as far as helmets go. Even if I had a bit more to spend on a helmet I would probably still buy this one again.
I'm in the north houston area and it's hot as h*ll. I have a black ovation schooler and I don't feel hot in it at all. It fits snug (as it should) and doesn't feel cheap at all. I think mine was $50-60. I've had it since last summer and it still looks New. I tried on a bunch of helmets at Charlotte's Saddlery in tomball. If you are close enough to tomball or Katy I would recommend visiting them to try some on. Hope this helps. :) Posted via Mobile Device
I have a Troxel Spirit and while it is a very serviceable helmet, be prepared to look like you another head on your head. They are much bulkier than they appear, so do try one on first.
Mine enters the room a few seconds before I do. :)
