I don't know if the larger population of Lusos would show them to be hotter than PREs but there certainly does seem to be lots of anecdotal evidence to that effect. Luso mare have the reputation of being the worst of the lot but I do wonder if that is because they aren't often ridden in Portugal and spend a lot of their time doing their own thing.
Rija doesn't have any Veiga at all but she does have most of the other lines - a bit of a Heinz 57, including: Andrade, the National Stud and Terry. She is loopy and getting loopier though. :

I do ride Spirit, she is very backwards of where she should be, but I won a training bursary from BAPSH so I'll be having lessons this year...PMG will soon get the pleasure of her company.

We do have a little blog on here but I'm rubbish at updating it. She isn't neurotic but she is still a bit of a madam ... I think it must be me...
As far as costume goes, no I've not done it before. I have the saddle but nothing else so far and my mum is making a costume but I need to buy the hat etc.
