The Champion Challenger you refer to is considered by some the best plane of the Champ line. It has the classic lines and is light with the 0320 engine. Basicly a hot rod Champ. They are good performers and roomy compared to the Cubs. I believe the PK1800 float would be your choice. Possibly the Edo 2000 but I am quite certain the PK is approved and the  better match. For skis I would think any 2000 should be adequette. I would rather be over-skied than under so if there are any 1800's around, which are quite rare, pass and go to a wide bottom Federal 2000 or Aero 2000 which are very common. The wood spar issue is a dead horse beaten to death. The Champs and many others have flown for 60 years. Many out of barns with lack of maintenance. A qualified mechanic and proper inspection will be required. If it passes and the spars get the mechanics signature, I wouldn't worry. Since you are over 100 hp you will also need to inspect once a year at annual. No biggie. Many folks when rebuilding a wing go with new wood spars if replacement was required instead of metal spars. They (wood) will last the life of the a/c like all the others wood spars have done so before. Wood has benefits over the metal spar which I wont get into here. If you go to the Bellanca website at www.bellanca-championclub.com there is lot of spar information.
There were a few wing failures due to spar fracture. Those were mostly in the Scout 8GCBC, and one 7GCBC Citabria. Most of these cases involved airbatics or loading the wing, a missed banner tow/pickup, and a rapid pullup during fish spotting activity. Stressing these wings which are longer and in a/c with bigger engines and not approved for airbatics such is the (Scout) was the NTSB ananlysis. As far as I know there is not a single wing failure doccumented to spar fracture in the Champ lineup. That encompasses 1000's and 1000's of production a/c. Buy the 7GCB!!!!
