Since this has been bumped up I guess I could give an update... I have since traded in 2 of my cheap doodles to DDL doodles. One of them I settled for a 4500'ish doodle as a compromise to go with a theme for that particular toon. The second I got an "always affectionate" 4998 doodle with no regrets in either case.
I now have 3 DDL and 1 Brrrgh doodle and they all perform great. I have actually gotten to the point of working my gags on the top floors of blds while going solo (I wouldn't recommend this unless your doodle is maxed in a trick or 2). They are that reliable once you get to know their limits.
All I have to do now is wait for 5000 bean banks on 2 new toons (spots vacated since transferring daughters toons to her own acct! With the 2 doodles I maxed for her lol) so I can have my doodle herd back (I love getting full laff back in 1 trick

)... until then 4 will just have to do
