Jenny -
In the for what it's worth category:
Valid Expectations is the sire of 26 dams of 23 foals, 8 rnrs (34%), 6 wnrs (26%), 0 2yo wnrs (0%), .86 AEI, 1.51 CI; 0 sw, Leading Earner: Believeinmenow ($75,961).
Taken from Eqineline stats at one of the many websites for VE as a stallion.
The reason I say FWIW is that VE is on the cusp of our finding out what sort of BM sire he might - or might not - become: the vast bulk of his daughters who raced and did well (a likely indicator of their ability to justify/attract good matings) may just be entering the breeding shed or having their first foals to race hit the track. On that note you might want to think about these statistics:
His female progeny have sold at auction as:
Weanlings 17 $463,700 $27,276 $22,000
Yearlings 61 $1,615,000 $26,475 $16,500
2 Year Olds 44 $1,534,700 $34,880 $29,000
Older Horses 3 $19,377 $6,459 $4,000
Broodmares 22 $903,800 $41,082 $15,500
(also excerpted from Equineline.com stats at his Stallion Register site)
As he stand here in Texas, we see a lot of the VEs at the sales and as a group they are always finely chiseled invidiuals - very attractive if a bit small - I can say I've never heard of nor seen a "rangey" VE foal. They are very typey as to how well knit they are made so hopefully if he passes that on thru his daughters you will get a good looker. I would venture a guess that a 'typical' VE daughter could use a stallion that throws some substance/size into his foals but not a gi-normous individual by any means. Just a stallion that can add to an already attractive physique and certainly not one that will 'downsize' your mare's contribution. As a regionally based stallion that has enjoyed HUGE support by his connections VE has done his share of producing runners and winners from runners - many at the allowance levels and with decent earnings but overall he is shy in producing top level winners/performers so I would look for a stallion that has that potential - i.e. to produce the 'big one' as well, after conformational match/running attributes match has been taken into consideration.
Personally, I think he has the potential to be a better than average BM sire b/c of his own female family being such a strong one. That and the fact that a good number of his fillies - like yours - have done well enough at the track as runners. Both traits - IMO - hint at the possibility of VE being a decent BM sire, but it will take another couple of years before we'll really know. Good luck with your mare!
