I prefer geldings over anything. Never ridden a stallion, but I wouldn't mind owning one. Geldings don't come into heat and get b*tchy on you [ not all of them, I know ]. I've ridden one mare and I didn't enjoy riding her while she was in season. I'm actually looking into a filly, right now, but that's only because I know they're well behaved - that is the bloodline they come from. I may end up getting a little colt, we'll see.

But yeah, geldings most deifnitely. At least from my 3 years of riding.
