I own three HH take downs, along with a couple one piece Hill's. Craig's take down bows are solid as a rock. No slippage what-so-ever. They only come in straight grips, either large or small, but there is very little difference in size. My Hill TD bows are:
64", 53@28" "Red Man" with extra Lam of yew; small TD grip; Ebony riser and tip overlays; sterling silver white tail deer on riser
66", 56@28" "Cheetah"; large TD grip; Cocobolo riser and tip overlays
68", 50@28" "Half Breed"; small TD grip; Cocobolo riser and tip overlays
The TD Hill is my personal preference. I really like the extra mass provided by the TD sleeve. In my mind it adds to the stability of the bow. I've had several people shoot these bows and they were all surprised to learn that they were take downs after there shooting session.
Good luck with whatever you decide. Craig is a great guy to work with and he will not steer you wrong.
