I ride a Lando Phoenix ( same profile as the TRP ) and a Rossi One Magtek.
The biggest difference I feel between the two is the Lando has a "looser" feeling, not quite as "locked in" a ride relative to the Rossi. I would say the Lando is a "more agile" ride. You will experience a different type of ride, but you won't give up too much of the stability you have experienced on your Custom
As for going short, the shorter the deck , the more agile it will be. Just beware you will give up some stability and speed the shorter you go.
At your size and weight, I might suggest that 153 is a tad smaller than you want to go. 157 TRP will "feel" shorter than your 158 Custom.
