Do you want to catch them?
Bring them for the gun?
Do care about obedience?
How is your terrain, thick woods, fields?
Personally, for catching I'd go for pure whippet, ibizan, small grey...for the gun basset or beagle, harrier, dachshund, leggy terriers...for obedience I would forget these breeds and take a catching collie lurcher. In very wooded terrain dogs that give tongue are way easier to work with.
Ibizan is disobedient but real nice and fast for catching and bringing for the gun, gives tongue as well but cause its so fast the hare might go further, make bigger circles giving
