Now, I've always loved SBR Formula One. IMHO, he's one of those rare studs that are true successful all-arounders.
Too Slick Two Watch looks like a mainly performance horse and something like him might have trouble being successful in WP, but he'd excel in anything speed or power oriented. He's got Watch Joe Jack in his lines which is a huge deal to me. My Dad had 2 sons of WJJ and they were both the most amazing horses. Their temperaments (one gelding, one stud) couldn't be beat. I had ridden both of them, even though I was only somewhere around 7 at the time. The stud, Watch Ole Man, I only rode in the arena around home and Dad used me to ride him for his sale ad video.
Olena's Holey Sox would likely produce the same type, great at power and speed events, probably not so great at pleasure.
Given the choice, I'd go with Formula One first if he complemented the mare, then I'd go with TSTW second. I like him better than the Olena horse, but that may just be because I love his lines.
Oh, and let me clarify about the WP thing with those 2. IMHO, they would train for it well and do it well for my taste, but I don't think it's likely that most judges above lower levels would place them well in a class.
