Definitely get 2speed & ride control, & high flow for future resale even if you don't need it now.
IMO, the hydraulic quick hitch is not that important...after all, if you're changing hydraulic attachments, you have to get out of the cab anyway to uncouple/couple hydraulic hoses, so what's the problem with also operating the manual quick hitch?? On non-hydraulic attachments I can open the door on my SSL & operate the manual quick hitch by bending down & not even getting out of the cab!! The other problem with hydraulic quick hitch is that it is a fairly expensive option, & depending on the design, it can be troublesome. Many OEM's have gone to an electric-servo quick hitch, not really hydraulic...do you really want those electrical components on the end of your loader that is usually in the dirt/muck/snow?? I think it is a problem waiting to happen!! Now, IF they made a hydraulic quick hitch that also included auto coupling of hydraulic lines (like is available on some excavator quick hitches), that would be worth considering...
If you need a grapple of any sort, I would urge you to consider a Demo-Dozer attachment. Google it...I think it is a unique, well-designed & well-built unit.
If you're going to be working in the mud with your CTL, then look for the most ground clearance, the most sealed under-body, & the most easily cleaned out under carriage. Unfortunately, I don't think there is one brand that has all 3. Be wary of hydraulic hoses thru the side body to the final drives. The side body holes let in dirt/muck, not to mention damage to the hoses. Some CTL's have final drives that are sealed to the body with no exposed drive lines. IMO, these are the best. For example, I just recently took a quick look at a Kubota SVL-95 v2 underbody, & the final drives were sealed & bolted tight to the side body & the undercarriage looked very open & easy to clean out...& quite rugged. I have no opinion on it's other features.
And lastly, if you will be working in mud by yourself, consider a rear mounted drawbar or winch (electric is OK), because you WILL get stuck/hung up at some point!!
